Merging licenses

Is it possible to merge two licenses. I have 4 lifetime seats and need another 4. I understand I have to buy the extra 4 licenses separately, but if I buy the extra licenses will they be added to the existing 4 or will it be a separate license?

Seeing as you have to update the lifetime licenses regularly I want to combine them so that I can update all at once. Is it possible to buy the extra 4 licenses and then combine with the existing 4, so I can update 8 at once in future?

I will do it for you. Can you please contact me directly on gary@emclient.com
