How can Admin see every record with zoho.loginuser active

I have a form that my salesmen use to ask for maintenance for our customers.
I used a zoho.loginuser so that each salesmen can see ONLY his entries.
Once they submit a form, I have to edit the entries in view mode, in order to let them see when I've processed their request.

PROBLEM: I can't see their entries because I'm logged in too, but with my userId! So I could see only my entries (which I don't need...)

Any suggestions?
