Reduce Contingency Fuel and Regulated Performance-Weights

Hello,
I have been using simbrief for years. It would be nice to implement the possibility to calculate an RCF situation, Reduce Contingency Fuel procedures with a DP (decision point), and other fuel planning particular scenery, like also the isolated aerodrome planning with PNR.
Then also the possibility do edit and set Regulated weights for aircraft, I mean to manually change the structural weights of the aircraft to be respected in flight planning phase, this due to performance limitedsituation, as for example landing on a performance limited runway for instance FMNN, where you must have a lower weight than the MLW due to short runway. Same for the Take Off Weight.
Then a more detailed mass and balance form, with the possibility to make a load sheet for your flight, choose male, famale, child and infant, bags and cargo loads. Edit OEW and implement catering with DOW
Thanks
Regards
