it would be great if there can be 2 tiers of "Group by" option, e.g. Group by Business units (tier 1 - custom single select field) then within that list, group by tech teams (tier 2 - custom multi select field)

Similarly, it would be great if we can do 2 tiers of 'Sort by" option, e.g. Sort by Status (Tier 1), then sort by Priority (Tier 2).

Additionally, it would be great to have an option to dictate/define the sort order of a field, e.g. status from "New -> Backlog -> In Discovery -> Ready for Design/Deliver -> In Design/Deliver -> Done" rather than alphabetically (perhaps via a dropdown with grabber on the side to move with the dropdown)
