Is there a way to hide zones but still use them for tracking?

I have my whole city divided with multiple zones, so that a user is not shown “away” but always in some sort of location that I set.

This creates a lot of clutter on the map. There is a switch to make a zone passive, but in that case it cannot be used for device tracking. And that is my main purpose.

It would be great to make a zone hidden on the map, but still use it for device tracking. Is there any way of doing this?
