Rotation of Group of objects

The ability to rotate a group of objects including Asteroids.

We created a new asteroid for a friend to start building his own base. As you know, we can't rotate the asteroid in-game when placing it. Sadly, the good 'side' of the asteroid is facing away from the light source. I rotated the asteroid 90 degrees (yaw) anti-clockwise. I did the same for the station that was on the asteroid... but they don't match up like before. Am I missing something?

It would be really really awesome if we could select 'Asteroid' and then 'Base' on the list, and then rotate them together. Or maybe there is a way and I'm just not familiar enough with the program to do it.

This issue may no longer be relevant or even fixable, as most worlds are now created with dynamic asteroids and these cannot be modified in the normal sense. They are a generated with a random number seed, so their appearance and orientation are not tied to physical point of reference.
Many games are still started with static asteroids in the center area however, but these would be rare instances.

The issue names no files, tests, or entry points; begin by locating the editor's existing object-selection and rotation workflow. Check how static asteroids and attached bases are represented, and define done as rotating the selected objects together while preserving their relative orientation where the world format permits it.
