to limit which trucks are available for an aircraft?
I second this request, but would rather have this option as part of the profile since the availability of specific classes of tugs is location specific, not aircraft specific.
Being able to define the available types of tugs for each parking would be great.
It could still be overridden if a specific aircraft does not support small tugs (like an A380) but in the cases where more than one model would be suitable, limiting it using a profile at the gate would be nice.
Having the huge trucks at very small regional airports is kind of awkward (same applies to passenger buses btw.).
