Yes there is.
The map will then show you them all (except disabled and archived, but you can add those in), and allow you to add them to VGPS.
EDIT: Sorry, I just realised you wanted caches by specific OWNERS mapped, not caches found by specific CACHERS. Oops. Target is right, a custom filter would be the way to go, with the Map Compare as above (but with your name in the 'profile name' box).
