You did. I created Cocoa methods to do just that, with John Timmer's help.
That part wasn't hard at all, if you keep track of your Objective C

super-fast Cocoa methods and reload it.

Then you may have to stay where you are "so far". There are some things you
just can't do with Studio data sources. Fortunately call method does provide
a way to access custom data sources when you discover you need them.
