Ability to assign an owner to a Group

So we are currently using Monday boards for tracking OKRs.
The way we decided to do it is to have Boards with multiple objectives, where each group on the board is an Objective, and each pulse in that group maps to a KR of said Objective.

This works ok, but we currently have no way of assigning an owner / assignee to a whole group, apart from assigning them to each KR / pulse in that group.

It would be nice to have assignees on groups.
