Ability To Add All Statuses to Grid View

We have the issue of our reps not being able to find clients after the contract expires because they are automatically moved to "inactive." I would like the client view to include inactive and terminated accounts via a toggle. The reps do not have access to the admin features to look them up by the URL in the list of all clients so a manager has to do it and send the link to the rep. We work with a lot of "inactive" clients so this is a rather large sticking point for us.
