Add More Baggage Carts to Service Truck?

[jfergTNYC]

So I haven't played this in a while and just got back into it. I see they added new service trucks (for bags). There are large and small varietes. Under the description of each, the large says it can pull up to 5 baggage carts, and the small says up to 2. I ordered some large ones, but they are only ever pulling one baggage cart, and thus leaving bags on the plane. I can't seem to find anywhere where you can add more baggage carts (so it is pulling the 5 the description mentions). Any help? Or are more carts going to be added later? (I seem to remember before the update, the old baggage trucks pulled 3 carts). Thanks!

Yes, carts are added automatically so you don't need to worry about it. Before it takes a job it calculates the number of required baggage carts needed.
