I can't seem to do that. One of the (admittedly a smaller one, but still a reason) reasons I tend to shoot more and more medium format is that 36 exposures is just too darned many. I end up with a roll of film in the camera for weeks, sometimes months. 12 shots in my Yashicamat or 15 in my 645 are a lot more reasonable for me. YMMV of course. I do load shorter loads of bulk film.
Yeah, I agree, long rolls suck.
