Many aircraft have a Utility Category Mass and Balance envelope within which aerobatic or semi-aerobatic manoeuvres are permitted.
As a minimum it would be helpful to be able to define the limits in the aircraft profile setup and have those values shown at the foot of the M&B graph so the actual values could be compared. Even nicer would be to plot the resultant Utility Category as a shaded area on the graph, so one could immediately confirm more easily whether the proposed flight remains within the parameters.
