Your best bet is to use the "Inspector" tool in the SketchUp plugin, which gives you access to all of the elements of the OS:Daylighting:Control (see the image below). The edit pane for the thermal zone(s) allow you to assign percentages of the zone lighting load to one or two daylighting controls (see the other image below).

P.S. If using the Radiance measure, I will go ahead and repeat the caveat: the OpenStudio Radiance measure simulates continuous dimming, regardless of what control type is selected, and only works off of one primary daylighting control per thermal zone.
