Theres a senario that has a db br 101 on both ends why can't senario planner have this as a formation option as well since there no cab car to use.
I believe Maik from TSG mentioned there were technical limitations atm, but I believe they do intend on adding it eventually.
I hope so, this feature would give the loco the possibility to be added on HMA, even withtou the cab car. And the IC would fit so well to the route!
