In the mod as it currently exists, you can create the giga version of the PLS from the vanilla PLS, and have separate tracks from there on. I think adding recipes to create the other 2 giga stations from their vanilla counterparts would be useful, esp. for upgrading a vanilla station to giga & for mods that add ways to obtain the later vanilla stations (e.g. MoreMegaStructures).
