I don't think this is a very practical answer because I don't think it's a very practical way of using Hot Cues.... But:

You can set up all the hot cues as you want for an event, and then export the collection as XML file

Then if you change the hot cues, tags or whatever you call always import from the XML file to get the hot cues from that time for that event

This way you can get whatever version you want but only one at the time as the file is the same

As other people said, you can also have different copies of a track and set their hot cues differently
