Status changed:
Open
to On Hold
This is being updated due to low engagement (comments & votes) from the community in the last 6 months. Please be advised that the idea has still been added to our developer backlog, but it will have less traction getting prioritised without more votes. A further review will happen in another 6 months where we will either close or re-open this idea based on the number of votes accumulated in that time.
