How to hide shapes on specific layers in non-top-level hierarchy?

Hi,

I have a display/hierarchy problem and I’m wondering whether Virtuoso supports it natively or if there’s a common SKILL workaround.
In our design flow, some layers are only meaningful at the top-level cell (think of pin-layers as a prototypical example of this).
Subcells may contain shapes on that same layer for local purposes (eg subcell-level testbench). When these subcells are then instantiated into a layout a higher level of hierarchy, these same shapes are also present.
While this is perfectly normal/wanted behavior for any other layer, for these top-level-only aphysical/tooling layers, this might actually be unwanted as they are effectively meaningless, but still clutter the view, making it hard to tell which shapes are actually true top-level. Ideally, I’d like a way to display objects on such layers only when they belong to the top-level cell instance.

I checked display and editor settings but couldn’t find anything relevant. 
I also tried to implement a SKILL approach where I would loop through hierarchy and try to hide specific shapes, but I only found a visibility property for text objects, making this strategy invalid.

So my questions are:

• Is there a built-in way in Virtuoso to hide shapes if they don't belong to the top-level.
• If not, is there a way to toggle the visibility of an individual shape by setting an attribute, or a display filter, or some other function?
• Any other ideas to achieve the same effect would be welcome as well!

Our project is currently using ICADVM20.1 but I suspect this applies broadly. Thank you for any advice!
