Think I'll have to live with it, If I drilled a hole in the seat as far back as I could it would still appear in the aft cabin. The wooden panelling is further back that you thinkMy Attalia has the same issue. I never thought about doing anything about it, but I suppose one could drill a hole and install a hose that drains into the cockpit somewhere near the scupper. I think the hose could be behind the wood panel in the rear of the aft cabin, so it would be out of the way. It doesn't seem worth the trouble to me though, unless someone has a more simple solution.
