Shared Workgroup Documents

I work in a small group where we each have CC for teams and primarily use InDesign to create weekly and monthly publications. These documents will have a primary document creator/editor but everyone needs to be able to access and edit as necessary. We would like to have a shared workspace that we can all access and edit the stored documents, where there is not a specific owner. We would prefer not to have to issue sharing invitations for each document stored. We also want the documents stored so that when staff turns over, eveything will stay in our shared area.

Can we achieve something like this with CC documents? From what I have read, CC documents are individually owned and each must be shared. I would appreciate ideas.
