Device Panels and Snapshots

I’m delving in to the under-used and rarely updated aspect of Cubase for interfacing with hardware synths - namely custom device panels.

I have some basic setups running, and have figured out how to record snapshots, but I can’t seem to find a way to dynamically switch snapshots within a session. Is there?

Also, it seems my snapshot selections (from the inspector drop down list) are not preserved once I close the session?

Thanks for the help.
