Analyse Button in deck

As a mobile deejay i often play request songs which i've never played before and i have a library of about 20000 songs.
Now, before i load a track to a deck i sometimes analyse it before i load it to the deck to make sure the beatgrid and key detection is ok.
So i think it would be a great function if there would be a single "analyse all" button in every deck to make sure, just before you start playing the track the beatgrid and key is checked one more time.
ps: only analyse the deck if the track isn't playing.
