Love the game but it needs a save slot where we can name the save and that way we can choose which name save we can go back and load.
Why do you need more than one? Your progress is always saved in your profile anyway, and you can have multiple profiles if you need them - the save game slot is just in case you need to stop mid-service.
It would be nice to have one for each route. I like the idea of starting service mode early in the morning and driving trains for a few hours but doing it on different routes and saving the progress for each route to go back to. I know you can pick each service individually but it is nice to image you are a driver and you have a mornings/afternoons work ahead of you, it just seems more seamless!
