Show background when there’s no foreground (#BETA)

Doing some testing on the new #beta and tried setting up our stream feed but can’t find a way to replicate the ‘show background when there’s no foreground’ option.
We use this at the moment to have some slides which pass through to the stream (by having no foreground) and then have duplicates with a transparent foreground which don’t.

This enables us to effectively run the service without needing to change the setup on the ATEM (as we only use one PTZ camera).
Can this still be done on the new beta?

Thanks for the report! I'll note the feature request, and we'll plan to include it in a future release.
