Click-and-drag highlighting in a simulation (Captivate 9)

Is it possible to correctly simulate a click-and-drag highlight interaction on a Captivate simulation?  I'm working in Excel and want students to highlight two columns by clicking and dragging the mouse.  I could just place a click box over both column headers that would work when they released the mouse, but when they're in the process of highlighting the columns, the students won't experience the actual interaction (where the columns highlight as you drag across).  For two columns, this isn't a huge deal, but there will be more interactions later on in the development of this course that will require more highlights than just two columns and I'd like to be able to simulate the actual interaction as closely as possible.

Thanks in advance for any help you guys/gals can provide!
