Hasta La Motion!

I can’t find a way to access the gridwarp points from a script.
I got as far as to access(print) the the grid array and value of the dstgrid or srcgrid but when I try to write to it it returns false….

to make things easy, this is what I want to do:

have a user button in a tracker or a gridwarp that automatically connects all 4 tracking points to the four corner points of a 4 point grid in the gridwarp…..does that make sense?

I know I can drag and drop the tracker curves onto the gridpoints, but it would simplify things if we could do it with the push of a button…also I could add easily some knobs for offset etc.

any help is much appreciated!
thanks guys….
