Im still in the interviewing process and wanted to know if I were to express interest in another specialty, would that be looked at negatively?

I applied to a company and had a phone interview with a recruiter. He said they have spots for the position I was interested in daily at different locations owned by the company/university. I got an interview with the manager of one area and I have a job shadow coming up.

I wanted to let him know that I was also interested in another area for the same position and to see if they had an opening now. I feel the other area would really be a great fit for me, especially with my past experience. Would that be frowned upon? Would it make it seem like im flaky or indecisive?
