Sort help desk split view by multiple items

In the Help Desk split view, you can sort tickets on the left of the email-like interface by a single item (last activity date, priority, etc.) without issue. However, I’d like to have the capability to do sub-sorts - that is, I’d like to do something like “sort by priority high to low, then within that constraint sort by last activity date oldest to newest” - similar to spreadsheet sort functionality you can find in Excel, Calc, or Google Sheets. This would allow looking at a single “assigned to me” view rather than having to have separate views for the “top-level” sort (that is, I have a view for each priority and then each of those views is sorted by activity date for the above example), and multi-variable sorting allows for a HubSpot client to sort by more than simply two variables should their use case require such.
