does the columbia art history program allow for dual degrees in other departments?

[fualmu]

I'm in a master's program right now (religion and the visual arts), but I'm starting to think about PhD applications, and I'm thinking about pursuing art history education. University of Arizona has a specific program that is for art history education specifically, so I'm considering that as an option, but I really like the programs and faculty in both art history and at the teacher's college at Columbia. There's nothing on either of the sites saying that you can do a dual degree in another department, but I would like to maybe start with a dual master's and decide which field I would like to pursue a PhD while I'm there. Does anyone know if that is possible? (also going to post this in the education forum)
