Is there a way to model multiple shapes on base plate in Hilti Profis?

I have a 24" x 60" base plate with two HSS sections welded to it 30" on center for which I need to design the anchorage in Hilti Profis. Is there a way to model more than one section on a base plate in Hilti Profis? Using a single section, I have to resort to a W30 in weak-axis bending to simulate the two HSS sections spaced 30" on center.
