I haz idea.
If you have a Campaign selected in the online master and you click “+Soundset”, how about adding the new soundset directly to the Campaign?
At the moment the workflow is a bit of pain in the bum. Create new soundset, come out of the campaign, find the new “Untitled” set and rename it, drop out of the creator and go to the Syrinscape “My Campaigns” to add the new soundset to the campaign.
This is the point in the thread where you tell me Syrinscape can already do this somehow…
