Possible to remove a device from My Devices list?

I just noticed that one of my old mobiles (which my son is now using) is listed in the Bitdefender Central "My Devices" view, however that phone had been wiped almost a year ago and Bitdefender is no longer installed on there.

This brought me to the question of whether it's possible to remove devices from the Bitdefender central list so I could re-allocate it to a different device, otherwise I would eventually run out of device licences.  I couldn't find a way to do it, is there a way?

Note that I intend to reinstall on his device anyway, but I would like to know the above for future reference.
