Allow color alts to be copied, changed, etc. without having to manually assign a group number.

Currently if you make a color alt group you assign a number, this is fine for small amounts of color alts.  Since the game does not yet support color group subsets (for example I have about 6 different flesh tones for some of my color alts), I need to have nearly 10 color alt sets for every main color set. It is getting pretty out of hand and since I'm pushing nearly 100 color sets for some of my species definitions I was wondering if the game could support grouping the color alts by their position in the species file rather than an explicit color alt number?

Maybe they're encapsulated in a <bracket>? I don't even know if this is possible.
