Put contact on Pause for X amount of time

Sometimes a contact will be traveling or not available for a few months.
We'd like to be able to put the contact on pause and set a date when the contact will go back to active automatically with a @mention to the Assigned To

Start by locating the contact status handling and the existing mechanism for notifying the Assigned To when a contact changes. Trace how dates and status changes are stored, then define the pause date, automatic return to active, and mention behavior as the completion criteria.
