I recently downloaded Phil Skene's latest layout and of course the first thing I want to do is to build a session so I can try it out. (By the way it's a neat layout and none of my questions here are directed towards it in particular or are critical of it). 
I save frequently as a session and especially once I start to programme that dratted ProtoLARS stuff - it always seems to make my system a little jumpy and prone to crashing.
So what has happened is that during one of these jumpy saves I must have saved it as a new route so that all subsequent session saves have gone to the new map. This makes me angry and resentful and tends to make me use colourful if socially unacceptable words.
From now on if I want to drive that session I have to load it from the new route map and not the original.
Is there any way I can move the session from the new route map to the original and delete the new route map? I really don't want to rebuild the session from scratch as I have programmed a significant number of AI trains and industries and I don't want to go through that all over again.
Cheers
