Add more functionality to Status "on hold" / "project complete"

I would like Aha to stop acting on a release if the status changes to "Project Complete" or "On hold / will not do". Today if I select on hold this has no influence on Overdue dates for example. Assigned people still get daily reminders - that does not make much sense. If we decide a release is to be on hold, Aha should allow the flexibility to stop any activity related to such release. Additionally a release on hold should not allow assigned people to work on To-Dos for example. It should be kind of blocked.
