Right now subactions are the work, assigned to different people and teams and with different due dates. The parent action serves to bundle them. Subaction due dates need to be easier to see

When filtering and sorting in table view, it's hard to spot imminent due dates in the subactions because:

Subactions are bundled under their action header

Everything is autocollapsed

Sorting and filtering is not ordered by subaction because the parent action is what it's sorted on

Solution: Separate columns for Action and Subaction so you can filter and sort directly on subactions
