Grouping Multiple Result Actions

It would be awesome if it were possible to group (sub menu?) many result actions into a nested set of round buttons in the mobile/Studio GO results panel.  This would allow us to have more than 4 buttons that look the same on the UI.

If this is unattainable, I'd also settle for losing the limit of 4 round buttons on the Mobile/Studio GO Results panel, it looks silly when you have more than 4 result actions and only 4 of them are round.
