Only charging my SE2 watch to 80%, is there an alarm to alert me its ready

I have a fairly new SE2 watch and have noticed it gets very hot if I charge it to 100%. So I try to only charge it to 80% each morning. But of course I have to keep checking the level to do that. My iPhone has a setting that almost always stops it charging more that 80% which I love! The watch doesn't seem to have that and I have found no way to set that up. I have looked for an app that could alarm me, but so far none seem to do that for the watch, just the phone (which isn't needed anymore (at least on my v15))

Does anyone know of a way to get an alert when my apple watch SE2 is at 80%??

Thanks, Bill

PS. no need to tell me about how charging it to 100% is the cats meow or similar. that's what I call disinformation from FB's.
