Situation:

I have built a large number of units made from small props all parented together. It is not feasable to convert them to figures... they work better as props.

I need mirrors of them.

Is there a way to mirror them all in one operation, and preserve the parenting structure?

PhilC has a very good prop mirror built into his Power Tools suite, but it only mirrors the selected prop... not those parented to it.

Any suggestions?

If not, I'm in for a long week. There are 250 of these things!
