Thank you. I ended up bodging a button out of an ide created virtual switch that webcore automatically resets to off as soon as it’s turned on. That works for my use case! 
I don’t know why I didn’t already try it, as I already had a similar thing set up with the physical switchbot bot that presses the heating boost on my boiler, albeit resets the status to off after an hour (which is the length of my heating boost).
Switchbot is almost such a great device, its 90% of the way there, just needs a tiny bit of dev work when it comes to smartthings integration.
