Grid Element Question

[Anonymous]

Hello! Is there a way to edit the length of more than one grid marker at once?
I select them all but I can move the node of only one of the selected markers. It's frustrating.

Whenever I have to do this I suspend Groups (the whole Grid System is grouped by default), then I draw a Marquee around the Grid Element Markers I want to move and use the stretch command to stretch elements within the Marquee.
