Beat match in Automix

Perhaps, there is another thread or a way to do this, but using DJay with broadcast, I love to set up the show first, I can inject a request or talk easy enough by protecting the active, turning off auto mix, wait to end of song, then allowing the new song in place of the current. However, mixing is poor (Automix and with my knowledge). So, in Automix, can it, or will there be a setting to match beats, keep the tone (no mousy if fast and no deep voice when slow), and then set a beat recover time so the song returns to its standard beat x seconds after the transition?

Ie. song ending in auto mix, new one fades in with same tempo and with tone correction for x seconds fade from current to new, then over the next y seconds, the new song goes to its normal tempo.
