That would actually be a very big change because that data is currently synchronized. I don't store a different tempo for the metronome versus what is shown in the song metadata. I could also see situations where people would prefer that the data be synchronized so they don't have to change values in two spots. I might actually argue that it would be better for you to use a custom field to store the tempo if you want it to be different than what it used in the metronome itself.
