Layers in layouts?

Not sure this is possible but seems like it would be a good feature to be able to turn layers on and off independently in specific details in a layout. For example see the fileav-base.3dm (294.6 KB)
The layout has a small inset of the perspective view where I’d like to turn off the layers I’ve used for dimensioning, but keep those layers on in the other details.
Is there already a way that I don’t see?

I think you might want to look at the command _HideLayersInDetail… This is also possible for individual objects via _HideInDetail, plus of course the equivalent _Show… commands.

Thank you very much. That worked. How does one discover these features?
