Multiple Rectangular Grids

Hello,

I am still a bit new to the Grasshopper and I have one simple question. I am trying to make several rectangular grids simultaneously, and later on use them for other geometric transformations.

Lets say I supply the Rectangular Grid Component with 3 different planes (and Sx, Sy, Ex, Ey have some single, fixed, values...lets say 4x5 grid). What I would like to have as an output is an array of 3 Rectangular Grids. Therefore, if I add 10 new planes, I would like to see 10 more Rectangular Grids. But the problem is I get an array of all the rectangles in all of the Grids together...so  instead of 3 Grids, I get an array of 60 rectangles. If I add 10 new planes, Ill get another 200 rectangles. 

How do I make it so that I dont have to think about what happens after the Rectangular Grid Component? When I add more planes I would like the same operations be performed on them without changing anything after the Rectangular Grid.

 P.S. When I try to extract a branch I get a bundles with "columns" - 5 rectangles....this doesnt help much...for every new plane I get new "columns" I have to deal with additionally...

Thanks!
