That's not quite what's being asked for. I think it's more like super+1 for "move workspace 1 to the current monitor". I haven't quite figured out how to do that in sway, although I'm pretty new with it.
In my scheme that move is just two key combos away, which seems fine to me, especially since it is rarely what I want. You could make it one key combo if you want, too, in a script if not in a single line.
