Normalise audio in Final Cut Pro

I'm running the latest version of Final Cut Pro, and I'm trying to figure out with a single click how I can adjust the volume of selected clips so they do not exceed a certain decibel level.

I don't want a response saying "That isn't what you want to do with auto because..." and I don't want to use another piece of software. I do not want to manually change the volume of each clip, I just want to set a maximum level that will not be exceeded.

Is this possible?
