Yahoo H2H divisional Playoffs, HELP!

[cbmets33]

Hey new to site me and a friend are trying to set up a yahoo league with 12 teams, 2 divisions and we want to set the playoffs for the top 3 teams in each division. Yahoo doesnt give us this option and insteads only lets us choose from divisional winners and highest overal ranking regardless of divisional standings...does anyone know if you can customize/edit playoff match-ups? If not this is a major flaw and it should be fixed.

also why doesnt yahoo offer 2 weeks championship round like they have done for years...its only 10 days this year, is that bc of the mlb scedule?

i really appreciate anyones input on this.
