Add more wagons to the cargo tractors?

[NumberNegative]

Is there a config somewhere to change the amount of ULDs / Baggage carts are loaded onto an aircraft?
My DC-10 here only loads one single ULD to each of the three cargo doors. I'd much prefer a cargo aircraft like this loades four or more to each like the default 747. Is there a particular stat of the aircraft that affects how many wagons of cargo are loaded?

Hi, go to the payload tab and add payload weight before starting GSX services, the amount of carts used are decided by how much weight you add to your cargo fields.

Winter OPS only 3.
