Well, huh Brenda!
By coincidence, one of my colleagues just showed me a working version of this exact usecase today. It's still incubating in our lab, but we will likely add it among our other solutions in due course. If you figure out another way before then, please let me know, but otherwise you're welcome to email me at doug.denhoed@atappstore.com and we can follow up at that time.
Regards,
Doug
