Quick filters to further filter the issues in the board based on additional sub-queries.

It would be useful to be able to create custom named buttons above the boards in each view, for example one called "Backend High Priority Bugs" that add or remove to the existing filter (for instance the view used for current iteration) additional conditions, example:

Filter from the View:
iteration: @Current
After using our custom button
iteration: @Current label: "backend" priority: "High" issueType: "bug"

We can do it manually but it would be convenient to be able to automate it with a button and don't repeat it every time.
