Xara :: Joining 2 Lines Together And Retain Original Paths

I wanted to join 2 lines together (i.e. end up with a single line). I know that you can join lines by selecting both then using any of the shape / line / brush tools to drag one node from line A over to the a node on line B (you get a little + symbol next to the mouse cursor once the lines can join).

This is fine is you want the final line shape to differ from the original 2, but what if you want to join 2 lines and retain the original paths?

I can do it by postioning the target nodes on eash of the lines almost but not quite touching then using the above technique but its a bit awkward and I suspect this isn't the best way to go about it.
