Gameplay Custom Rvds For Timetables

Is it possible to copy and then edit RVDs for service mode timetables, and then distribute them with the timetable? This would help solve the issue of unwanted trains substituting into timetables and also, fixes the issue I'm having with electrification requirements on Niddertalbahn.

 

yeah this should be possible, i tried it on my timetable and so far it is possible.
