ok, I actually just tried it! It actually worked!!! 
Which is funny because you don’t get an indication that you can drag anything when there is only a single dongle connected - e.g. you can’t drag something from the dongle to the software licenser, so I assumed this wouldn’t work!
So fair play for bringing that up, that was an amazing piece of advice - have you done it before yourself? I could actually imagine not many people even having 2 dongles. great workaround and actually quite easy once you know that it works. Fair play!!
