Unable to set wall top constraint

Hello, I’m exploring the trial as an option to convert CAD files to Revit and I’m not seeing the option to set the wall height constraint. It’s not there at all.

Also: is there a way to do this with multiple CAD levels at one time, or do I need to select them one at a time?

Hi, I am also running the trial version and cannot see the top contraint in parameter setings
