Seachable Event Tags From Inbox

In our business model where we are renting space in resorts at the time of the request there may be no availability.

Use case.
Let's say in July someone asks for a resort space during Christmas week. At the time of the request,

there was no availability. It happens quite often that our resort rep may call us in October and tell us of a cancellation and open availability. It would be stellar if we could go to the search bar at the top of the inbox and go to "Event Tags" select Christmas Week and pull up a list of several people who requested this week. Thus, saving us hours of one-by-one searching through hundreds of emails.
