Priority Filtering - Filter by "In Progress"

Currently, you can filter the “Priority” column by “All Labels” or “What’s Done.” There is no way to filter the “Summary Row” (the row at the end of the column showing a mix of the various colors assigned by label (e.g., low, medium, high)) by what is currently in progress.

When my groups are minimized on my board, I want to be able to see the colors in the Summary Row for only what Projects are in progress (i.e., not marked as “done”).
