Your workflow sounds entirely possible but as I see you are working with Support on this, I will let them dive in to make sure your Zap is set up just right.
I’ll be on the lookout for their response and circle back to this thread once I see it come through to share with the community!
I'm checking in with you here, since I don’t see a response to the message that our Support team had sent you. Have you managed to resolve things or did you still need help here? Please let us know :)
