Resource Planner - Customise Report (use scenario)

Could we please get an ability to create our own report (kind: Resource Planner) so we could pull all data presented within Resource Planner as per our needs? Currently we cannot customise it at all. It would be good if we could create a report and pull the numbers from Resource Planned and group them or present them as we want - within a chart, matrix grouping etc. We're able to do it for Legacy Resource Estimates and tailor it to the view we want to see it.
