Hello everyone!
I'm trying to create a thumbnail image in the same layout - is there a trick to shutting off certain layers in just the thumbnail image?
There are cities (green dots) on the larger version of the map - I want to shut off the cities for the smaller map just because it looks silly:

I tried turning off the layer in the thumbnail version - but it will turn off on both maps. Is there a way to turn the layer off for the thumbnail but not the big map? Locking the Map Frame groups doesn't seem to make a difference, so not sure if it's a separate setting.
It's probably something really easy. Thank you for the help!
