Change All Manual Junctions to Automatic

Any way of doing this using RW Tools, please.
Not the cosmetic aspect of junctions, but the actual functionality.
I have a freeware route from way back which has manual junctions on the main line.
Which are not a good idea for creating standard scenarios.
As the AI will not consistently path through them.
Is there an entry in the track file that i can mass convert in a similar way to swapping track types.
Thanks very much,
Mike.
