Why is integration with Bridge not promoted?

I received Expression Media - as a bonus - I guess. But I don't want to change my workflow that is based on CO5->Bridge->Photoshop. In my flow I often need to go back to CO5 from Bridge to redo a raw-file.
Activating CO5 from Bridge opens CO5 with the last Session on. This is ok, if no Session exists for the loaded folder. If no Session exists in advance, I add a new Session. After having named the new Session, everything is zeroed, my loading disappears, the folder-tree collapse, and I have to reposition manually by clicking through the hiearchy. This is really boring and quite unlogical. Why are my existing Sessions not available from a list, and why is CO5 not recognizing my loaded folder right away and prompting with the related Session?
Photoshop is integrated with Bridge - not with Expression Media. The energy used to promote E.M. should be shared between E.M. and Bridge. In my opinion Bridge is more used as organizer than E.M.
When I suggest this to helpdesk, I am teached how CO5 works - this integration problem seems to be of no interest.
