A new feature of SEHS is the dynamic PIS for trains/locos. It would be amazing if this feature was backported to already released locos/trains with PIS aboard. This would add the most value to the German locos/trains, because they are used on various routes. Imagine having the correct destinations for RE 1 on Cologne - Aachen (Dostos + 146.2) or the S-Bahn services (422). Working PIS on stations is another topic but it would be definitely cool to add those to existing routes.
