Talking about graduate school in undergraduate admission essay?

Colleges and Universities A-Z Carnegie Mellon University

So my first choice major is Mechanical Engineering, but I also intend on getting a masters in Aerospace Engineering. Most of my extracurriculars, like RC plane building, are more related to aerospace.

For the Carnegie Mellon supplement, would it be appropriate to talk about my intention of getting a masters in Aerospace, given that CMU doesn’t have ANY Aerospace Engineering program?

While it is good to have long term goals, I don’t see how graduate school is relevant in undergraduate admission.
