We will prioritize the features every release based on the demands, and we do not have an immediate plan to implement this since we committed with already planned work. So, this feature will be available for any of our upcoming release.
Please cast your vote to make it count and if you have any more specifications/suggestions to the feature request, you can add it as a comment in the feedback portal.
