Offline Activation For Full License

When I doing Offline Activation for Full License (Not Trial Or Extension) ,How can I save the Activation Details such as Email , It's means that there is a way to do Offline Full Activation in the same way when doing Offline extension and save the email in LimeLM Dashboard?

I describe the steps :A client who wants to activate offline.1) The client sends me a ActivationRequest.xml note2) I enter the LimeLm system page for Manually activate or deactivate3) I choose the file that the client sent me and create an activation file for it. At stage 3 I create an activation file for the client, there is no place to enter more details about the client even does not have to enter his email.And even when I create the activation file, I can not see any details about the activation I made from a file in the Product keys page.

This is important to me because if you assume a customer has made offline activation.After a while he said that his computer had been "burned" and bought a new computer(when he was lying and wanted to use this license for another computer), how do I cancel the old license when is not listed in Product keys ?This is the use case that I am afraid to happen to us.
