I have the same set-up on my Sprinter 27 and it is a pain in the butt. I bought a second hose and keep it attached to the galley drain, which is the one below the coach/dinette slide-out. I keep it connected and open. When I need to drain the grey and black tanks, I just swap one hose for the other at the sewer end. My friend wants to run a pipe from the galley tank to the grey water tank. Not going to be easy.
