I am not sure that it helps you. It might confuse the faculty member and, in some cases, may be presumptuous that you will gain acceptance. However, the PD might see clearly where you may fit within the institution if you matriculate into their program. I believe that that effort is a critical interaction that should happen once you are accepted, and during the decision process of selecting programs.
If your lab has a collaboration with a particular faculty member in that institution, that is a bit different because there is some common ground already.
