Mate & rotate a body

Hello;

      In adding an additional part to a part etc., I see how you can rotate a body & accept that, & how you can mate a body with a couple mates & accept that, but can't seem to do both. When I go to edit this, it wants to start over, so I can't seem to do both the rotate, & then add a couple of mates.

What am I missing?

Thanks, in advance for any input;
