Canon MP560 scan to Mac (PC) does not show active user

My wife and I share the same Mac Book Pro. When I try to scan from the MP560 via wireless I do not see my wife's name in the list of destinations to scan to when I select scan to PC even though she is the active user on my MacBook Pro. It does show my name as I am logged (and admin) in on my MacBook Pro (but not as the active user). When I scan something to my name it saves to my user account. I want my wife to be able to select her name and scan to her user account.

Thoughts, comments, advise, much appreciated.
