Filter Tickets by SLA based on Customer. There is currently a "Rank" field but it isn't customizable and if you create a custom field for customer you can't use it to filter in the ticket view as only ticket based custom fields show up in the filter.

I'd like to have the ability to create a saved filter for each class of ticket (Platinum, Gold, Silver, Bronze, etc) for tickets to use the SLA prioritization that already is connected via the customer's default contract to show how much time is left.
