Any way to get more uses for Cha+X / day abilities?

[Belabras]

Other than raising Charisma directly, are there any ways to get more daily uses for things like Bloodline abilities that are Charisma Mod + 3 / day ?
Traits, Feats, etc?

[Chess Pwn]

Some races have favored class bonus options that do this.
Elf -- Select one bloodline power at 1st level that is normally usable a number of times per day equal to 3 + the sorcerer's Charisma modifier. The sorcerer adds +1/2 to the number of uses per day of that bloodline power.
