Please include SLA in View Conditions

Feature Request Summary: 

I would like to be able to use: 
Whether a ticket has an SLA set
Whether a ticket has an SLA breach

as conditions for Views and what tickets show up. 

Description/Use Cases: 

SLA is an attribute property of tickets. Not having it be available as an attribute for conditions to apply to a view to, greatly limits the ability to use this. 

Business impact of limitation or missing feature:

This would be massively helpful in finding tickets that are missing SLAs, and setting up views that focus on the length of the remaining SLA (for example, an all "SLA broken, triage this view first" view). As Zendesk is removing offset pagination and suggesting users stop having such large views as a matter of handling this transition, this necessitates being able to break up existing queues into smaller parcels. SLA really necessitates all like SLA tickets being in a single view, since Views have no conditions for SLA. This puts you in a catch-22 with the upcoming update, if you use SLAs, you can't really build smaller, more focused views, because there's no options given for views to do so with SLAs.
