Basically, this file is what the game draws from to give you the options you see in the character creator. The creator itself is in no way limited to the number Bioware gives you. You can have two presets, or two hundred. You just need to put them in there.
First, find your file. Apologies for my mac-loving friends, but I know nothing of the apple beyond my cell phone, so I've got no idea where yours is. It's wherever your mods live.
It should be somewhere around here: documents/bioware/dragonage/packages/core/override and it should look something like this:
Don't just double-click the file- it'll open in your default browser which is of no help to you. Open it in notepad. (not word, not notepad plus, not notepad with wheels, just vanilla notepad. Trust me, the fancy versions don't like it. No idea why, but I've tried.) I think the mac equivalent is textedit. You basically want the most vanilla plain text editor you've got.
First thing. Save a backup. Just in case.
You'll see something that looks like this.
Don't make that face. It'll freeze that way and then where will you be? It only looks scary. It's trying to trick you, don't listen to it.
So, you've got your file open. Time to add some heads!

That should get you started. Take your pick. Take several!
Now you've got a couple .mop files. They may or may not have unique names. They may or may not have the same names as the preset. What you want are unique names. If they're unique names go ahead and keep them (if you want). If they're named something like 'EM_CPS_P03' change it, since that's set up to replace an existing preset. Name them anything. Name them after your lunch. Just make sure they end in .mop
Go to the chargenmorphcfg file open in notepad. Find where they go. The preset faces are first, and their order is human male, female, dwarf male, female, elf male, female. Make sure you put them in the right gender and race spot or the game will get gumpy. And then it'll crash.
See how the format is? Follow it, and pop them in after the existing faces. Go nuts.
[resource name='yournewface1.mop' /]
[resource name='yournewface2.mop' /]
[resource name='yournewface3.mop' /]
Like such but with < and > instead of [ and ]. I personally like to make sure the names contain the race/gender prefix bioware already uses, but that's optional. You don't have to worry about subdirectories here. As long as the files for the heads themselves are in the override folder you're good. The important thing is that the names in the file have to match the names on the .mops you downloaded. When it looks in your override folder for them they'll have to mesh or it won't work.
Once that's done you should have something like this:
It is a huge, unruly, boring pain in the ass. But it's EASY. Time consuming, sure. Complicated? Not even close.
Finished? Go to save as, select 'all types' from the dropdown, and double click on the old chargenmorphcfg file. Overwrite. (since you made that backup, right??).
Open your game. Admire the new hotness.
Warnings:
A lot of head mods out there (hurhur head) will require you have other mods installed. I counted a grand total of TWENTY THREE required by Female Faces Compilation alone. Make sure you read all the instructions. It may require you have a pineappletree's eyes, bidelle's cosmetics studio, more hairstyles, tucked hair, LOTC hair, wyld tats... you get the point, yeah?
See? Really, really simple, isn't it?
