Function decoder connected/disconnected from loco

[Andrzej]

I'm looking for such operation when locomotive leaves cars, is no longer coupled to specific function decoder, and then another locomotive comes, and takes control of the function decoder.
I think there is no such automatic operation in the current version of WDP. So, is that possible for the next one?
Perhaps, locomotive editor would allow to add more function decoders, and only one would be active at the time. Then automatic operation would just activate/deactivate specific function decoder for locomotive.
