The issue I take with this is that location will almost always play some role in weighing options for people, and there isn't a very reliable way for discerning that, short of someone straight up telling you "I just want a program in this specialty in this particular area and that's why I want to come here." That's not to say it will always be the deciding role - someone could despise cold weather but rank B&W/MGH number 1 because of the program and be willing to suck it up, but maybe they'd be less willing to do so for St. Elizabeth's if they have other comparable options in locations they prefer. If you gave a bunch of people going into oncology specialties a choice between MD Anderson and MSK, much of the divide would likely be due to whether they'd rather be in NYC or Houston. Switch up the options but with the same locations, and maybe the choices change, depending on which 2 programs are being compared, but there will still likely be an influence of location. I can understand trying to gauge interest in your training, but trying to parse out geographical preferences like this seems more unlikely to really help much, and instead risk losing out on good candidates.
