Changing Sides/Attachment Point in Subassemblies

Have you ever wanted to change a subassembly from the right side to the left side or vise verse. You have probably tried to do it in the properties window and noticed it is greyed out, it just won't let you do it.

There is a way to change it by going into the subassembly properties dialog box (just right click and choose subassembly properties...). Just go the parameters tab and click on the side box and choose left or right.

You can also change the attachment points of curbs in this same manner.

And since it was overwhelming in the poll questions to add pictures, I did this time.
