We're deploying a large number of sites which we'd like to organize according to their site codes.  It would be excellent for organizational purposes if we could tie a new remote office to an existing DS without having to deploy a new DS. 

For example if we have a DS in a hub site where multiple primary offices terminate to their local MPLS cloud we'd like to have a DS there which services multiple site codes.  With the current architecture we have to assign multiple sites to the site with the DS. 

Hopefully this makes sense.  Please let me know if you need additional information.
