So you’re talking about a very specific 1 off scenario of a dropdown when creating a notification service call?
I can’t answer that at this point; It’s the only thing I’ve tried to do.
I think you and OP are talking about very differnt things. You just want an easy way to output the current time into a message/notification. OP is talking about adding times together (calculations in templates), which is a pain.
I don’t think the functionality needs to follow the input field, perhaps built as helper tool? I don’t know, I’m just ‘spit balling’ at this point.
You’re correct.
