Matchington Mansion/Homescape log in help needed with facebook

I use both of the above games. I use different facebook accounts for each game because I play with different set of friends/players with each game. In my Kindle it allows me to use 2 different FB profiles, 1 for each game. I just got a new Ipad and no matter what I try, it defaults to the same FB account on each game. After entering the login for one game it seems to have set that log in as the default, and no matter what, it will only see and log into that one FB profile on each game.

Is there a way to log into each game with different FB profiles?
