Crew count and weight to f/p and airframe editor

For airliners, it doesn’t matter much, but as for general aviation, the crew count and its weight can make more relevant difference to maximum payload and to MTOW, no? So, shouldn’t Simbrief flight planner make available crew weight/count fields at ? We can currently add crew weight to the Empty Weight, but it would be easy to SimBrief calculates it based on informed crew count than we always remember Aircraft Empty Weight and sums to it variable crew count (1 or 2) and its weight. Also, when exporting/filling f/p to would say IVAO, SimBrief always add +2 for People On Board, expecting a fixed crew of 2 people, what’s not always true for general aviation even less for airliners.
