Using Zoom and Pardot with multiple business units

[dhigginsCE]

We use Zoom webinars and Pardot (aka Account Engagement). Our Pardot instance has multiple business units, each of which host webinars. We like to use Pardot form to capture registrations, so as to keep our corresponding SF campaigns and Zoom webinars in sync. 

I have had limited success in getting the Pardot app in the Zoom App marketplace to work. A big limitation thus far is that I cannot seem to integrate multiple business units at once. Does this app only support one Pardot business unit at a time?
