Merging Em Client mail on two computers?

My wife uses eM Client for her email. Her primary computer is in the shop. If I install Em Client on another computer and she uses it until her computer is fixed, is there any way to combine (merge) the mail on the substitute computer with the mail on her regular computer when we get it back?

Thanks for any help that is forthcoming.

if you are using IMAP, everything remains on the server so it will automatically re-synchronize. In case you use POP protocol, you can temporarily change your account options to not download messages from the server, or you can export them an move to her regular computer manually.
