So, somehow after unlocking T2 batteries, it defaults to building the second station BP with them, but there's none with the T3 batteries, and you can't use the "build station" button to build a custom station. You can go into the BP menu and select your custom station and build it, but then when you place it, there's no way it's going to be in the centered location that it default builds (which I want). You can use the "build station" button, delete it before it builds, then build a module around the core, but this is slightly tedious, and you can't do that for void stations.

If you could select which station the "build station" button builds, or if you just automatically build in the center, I'd like that. I mean, what's the point of being able to build off-center to begin with? There's nothing out there to build close to, and there doesn't seem to be a direction limit.
