Hi Robert,
I've been loving using your program lately – it's been great for generating operating sessions. I have an idea for how to tweak the systems of assigning cargo to cars, if you don't mind hearing me out.
Some cargoes can be carried in more than one type of car – oftentimes lumber was carried in both boxcars and flatbeds, even gondolas on occasion, and similarly, both gondolas and hoppers can handle coal. I think that to represent that in a streamlined way (especially with trains containing more than one carload of the same cargo), it would be nice to have the 'Car Type' in the cargos tab be a checklist rather than a single-selection dropdown, if that is feasible to set up.
Best,
Miles
