In-Place Hold Query Based on Assigned Policy

Is it possible to create an "in-place hold" query that places a hold on all items matching an "assigned policy/personal tag?' If so, how do you do it?  We have three possible assigned polices. If staff do not select a policy, their email is purged in 90 days. If they do select a policy, it's an important message and we want to place it on an In-Place hold for the duration of the Assigned Policy.
