Method to quickly choose a level of elements to show in view (eg L3, L4, Base elements)

Currently, the only way to show all layer elements of a dim is to select them in edit view, or slowly click through every one of them to expand it out.

This is time consuming in designer, and quite impractical for published views (reports).

Can there be a function added, either on right click, or in the header, to expand an element out to the desired level quickly? (eg L3, L4, Base elements)
