allow us to control which store dialogs can be seen from a document tray
document trays are used for different things. eg. invoices coming in to one facility go into a particular document tray (from C2Mailor or from DWImport from a hotfolder linked to that facility's MFP, or users at that facility only have access to that C2O configuration, etc). Wouldn't it be great if any of those invoices could only be stored using one particular store dialog (eg. the Invoices one), even if that particular user also had access to a store dialog for contracts or other documents that never ended up in this tray? That would simplify the user's menus, reduce possible misfiling, and add some elegance to the solution (no more "why can I see ALL the store dialogs here? I only ever need this one when I'm in this document tray" questions).
