Edit docking port roll value?

[BuriSalt]

So I decided, for some reason, to build a giant ring in space. It's made of nine identical sections connected by angled docking ports.

After a lot of lifting and docking, the whole thing came together, but by the time I was four or five sections in, physics was beating up my CPU pretty bad and now I'm getting only a few FPS.

The problem is that on some of the docking connections the relative roll between the connected ports wasn't perfect, and the whole thing looks a bit stomped on. With the performance I'm getting I can't disconnect, fine tune roll and reconnect very easily.

Is there a way I can edit the quicksave file so that the relative roll between each of the paired docking ports is lined up perfectly?

Any save file master hackers want to take a shot at this?
