Grid custom layouts 4.0.1

[Ualaa]

Ideally, I'd like Grid to display my five toons, in column one.

And to show the rest of the raid in columns two through five.
But to only display as many columns/frames as the number of toons in the party/raid.

My five chars in column 1 (in the order I choose), rest of raid in columns 2-5. Someone please write this!!1!
