In V/G dialog in rvt tab set the Link to 'by host view' and hide will be allowed.
It does look like custom will also not allow this if a linked view is selected.

I hope this clears up the confusion.
I want to refine the solution:
In V/G dialog in rvt tab set the Link to Custom, and on first drop drow down menu - Linked view - set to NONE.
then you must customise V/G, and hide link by element
