Hopefully a fairly simple question, can I define multiple WebPartManagers for a site? I know they're defined in a master page and would like to add an additional one with some custom connection logic. I've read however that I NEED to use an SPWebPartManager if I'm using WebPartZones.
I can't seem to get SharePoint Designer happy when I try to add a custom one myself but haven't figure out why yet, so I thought I'd pose the question too.
