How do I merge the floating license X of Quartus II managed by server A into the floating license Y of Quartus II managed by server B?

I'm very sorry for hijacking an old subject, but I have the exact same issue, and could not find a satisfying answer to the problem. We also have two licenses administered by two different people that we need to merge, or at least run on the same server, is there a way (official or unofficial) to do this? or to merge our licensing accounts to generate a new file? Or at the very least a phone number to call?
