Have I something to explain? We need it. More I don't need to say lol :P Maybe like the consist editor from the Train Simuator 2021?
Yes we need this and maybe we need an Editor for engines also saying you want Your AC4000CW and maybe you want to have 3 others helping with the consist put what you want on the tracks.
That was normally the plan, but they didn't have enough time to make it so they made the 'scenario designer'. But it would be really cool if we have that.
