this is similar to Define group color during group create so i suspect the answer is the same.
i need to be able to set the position when i create a group (and the color too). currently new groups pick a random color and are created on TOP of the board.
something like
mutation { create_group ( board_id:xxxxx, group_name: "New Board", **position: xxxxx, color: xxxxx**) { id } }
or much BETTER, add a mutation for update_group that allows those to be set. that way we could set color and position on an existing group (or freshly created one) without needing to delete and recreate a group.
