Panelling tools grid: cage editing

I have a question about panelling tools grids.
I have been trying to modify a surface based grid made in panelling tools. Either grouped or ungrouped, it doesn’t seem possible to be able to cage edit the points. Soft move works, but is there another way to directly transform this grid like it was a regular surface?

Have you tried to RecordHistory when first create the grid? If you do, you should be able to edit the surface, and the grid will follow. Does that help?
