Through Bolt Connections in Simulator

Below is the scenario I want to simulate:

I'd like to replace the screw and nut with a single bolt connection, but it won't allow this as they both touch the same body.  I know I can cheat this somewhat by creating two connections that bolt the channel to the inside of the tube, but I was wondering if there was a better way.  This has to be a fairly common scenario.
