As it stands, we can only edit a few things about a creature when we add it to our sheet. AC, HP, creature type, we can edit these things, but i would like to also be able to edit ability scores, bonuses to saves, skills, attacks and damage, save DCs, hit die count, etc. 

It would be great if we could set modifiers for certain catagories in homebrew. Like, every "Summoned" creature has a +2 bonus to skills it is proficient with, or has a bonus to weapon damage equal to half of the PCs Charisma modifier.

Basically, its gonna be really annoying if we have to make homebrew copies of every creature we summon that have special bonuses. Even existing things would benefit from this change, things like undead and demons getting an Oathbreakers CHA mod to damage, or creatures conjured by a Shepard getting +2 HP per hit die.

I'm pretty sure you can change all those as well. The changes per-campaign is a cool idea though

My guess is their background software isn't setup to handle modifiers like that right now.
