Deeper Cash game (80-200bb)

Hi team!
Is it possible to make game more optional?

1. Adding rebuys up to 200 big blinds

2. Would be nice te make min buy in at least 80? 40 seems to low espessialy starting tables in games such as plo6 - ppl buy in for 40 play few all ins with close equity and run away with almost no risk mathematicaly.
