Subtasks - Add Group Highlight to Update Field

I would like to request adding the same group highlight as features to update fields. i.e. adding tags!! I need tags on my subtasks, but you either have to add individually or go back up to the date header, unclick the sort arrow (which is always on), then scroll back down to the section, click the carrot next to the Task with subtask to show subtask, then highlight and update a group at a time. TOO MANY steps. Can you just add this same functionality to the subtasks as the task level?
