How do i rename a synced folder without unsync it

I just dragged my “windows my documents” folder to seafile and shared it with my wife.
My wife did the same,…

Not a good method, because now i have 2 folders in my seafile client called “documents”
So i want to change ONLY the name it is displayed in Seafile, without forcing myself and my wife to create a new mapping.

Result should be that seafile is displaying the name of the original owner (resp. me and my wife).

Can i simply rename a allready synced file in some settings/config file of seafile??
I allready checked the seafile folder, and the ccnet folder in my user profile, but was unable to locate a textfile i should be able to edit??

Kind Regards
