Hypo, all you have to do is select the add poll button. I added the "other (please specify)" for you and then selected it. There is another option that I use. First, I set osmode to 6175, because I use polar at 15 degrees, which acts as nearest. I force feed perpendicular, because running it constant cause problems. It forces itself too often. Also, some options don't fare well in running mode, i.e. parrallel. Plus, I don't use mbuttonpan in pan-mode, which allows me to hit the middle button and avoid the use of shift-rt click. Then, I've grown accustomed to knowing the mnemonic of each snap and therefore, if I want to force perpendicular, I middle-click select p and get perp. Very quick and efficient.
