Dawned on me the other day that you can do this! So here it is in case anyone will facepalm realizing it like I did.
This uses IFTTT, an input Boolean, input_ select, and a couple automations keeping track of the last motion scene and matching that to the Boolean that IFTTT triggers. This was thrown together in about a half hour so I’m sure it could be improved a little, I’d like to prevent the input select from updating every time I pass a sensor for example.
First you need to make an IFTTT skill:
IF an alexa timer goes off, THEN (webhooks)

It’s been working great so far! Sometimes IFTTT can be a little buggy or slow but it’s not like we have much choice right now.
