If you change the style the Re-Route will still stay sending to Halion.
You can use File > Import > SGU/MGU Song and chose what elements you want from another SGU, like chords (see below).

You can copy the chords/song info from another instance of Biab.

You can also use this to inject saved chord progressions/song info/style
