Is blanking out a section of the drawing possible (in a sheet for example)?

Hello everyone,

I'm relatively new to working with DraftSight and I was wondering if there was a possibility to not display certain entities or to change their color without changing their layer (at least not in the actual model) while leaving other entities of the same layer in their original state? The actual problem is that I'm working on a groundfloor of a bulding with several appartments and I would like to highlight one of them in a different color in a viewport sheet for printing or just not display the other appartments, either way.

Thank you for your help !
