For example, I want to un-hide a component in a large assembly by selecting the component(s) from within another display state where it is shown.  I used to be able to do this in Pro/E and it would save quite a bit of time in working in large assemblies.

I can do the similar action for suppress/unsupressing parts in the Component Properties but the identical looking function for display state doesn’t actually let you select a state to change.  Even so, doing this in Component Properties is a pain.  In Pro/E I used to be able to select a number of components and then add to another display state.
