How to change Presentation in PPT Add-In

I've added few slides from a test StreamAlive presentation into my PPT slide deck to try it out. I've deleted those slides from my PPT and want to connect a different StreamAlive presentation inside the PPT. But, when I click the 'Back to my presentations' button on the StreamAlive Add-In, it jumps to the My Presentations screen and immediately back to the previously chosen presentation.

How do I switch the presentation that the add-in is connected to? I don't want to recreate my whole slide deck, just the StreamAlive slides.
