Does anyone know how to set this to upgrade whatever gem has the highest % chance of upgrade? I want to set my best character to level several other characters gems, but it keeps trying 3 times to upgrade a few rank 30+ gems and leaving all the others at rank 3-15 alone. I want to get them all to 25 before really bothering to push one to the highest. I know it could do all to 25 in the time span it would take to get one gem to 40.
