Does anybody else find it frustrating in Scenario Planner that you're quite restricted in the paths and platforms you can route trains to and from? E.g. I was trying to recreate weekend engineering works by scheduling a Rainham to Gravesend shuttle on SEHS, however there isn't an option for a train to leave Gravesend from the Up platform in the Down direction using the crossing to the south of the station. Instead you have to put the train into the Up platform and then start a new service in a different unit on the Down platform. I've noticed the same on ECW at Polegate which is also used for reversals during closures. Am I doing something wrong or if this not possible?
