dynamic infoview inbox destination of published reports?

I'd like published reports to be automatically organized in the Inbox of recipients; that is, I'd like to run some code that decides how to organize the reports in subfolders and delete old versions of reports.

What are the appropriate hooks for doing this?

A post-publication event? That would invoke some code to move a report to a subfolder.

A hook to dynamically specify the destination? That is, register a managed destination that would apply some built-in delivery rules.

Or will we have to schedule some code to run that drives everything: executing the publication and then doing whatever Inbox cleanup for the recipients?

These are newbie questions. Thanks in advance.
