I'm trying to get from Kerbin to about 10km from the Mün, then come back. Easy peasy, except I want to save a whole bunch of fuel by going in the cismünar way so the Mün's gravity assist gets me back to Kerbin instead of into deep space. I can't seem to find a way of doing this with maneuver nodes, which only seem to show reaching the Mün at all if I go around the transmünar way and get the gravity assist into deep space. Is there something I'm doing wrong here?
Here's an graphic for the equivalent orbit in the Earth-Luna system:
