Possible to log 'misses'?

Just in case, I'm wondering if it's possible to log one's misses in for a song/session -- maybe Rocksmith generates a file like this? It must keep some kind of record in order to display the exclamation points, right?

I'm having trouble with the sync to a song -- I know the song really well, but I still get misses, and I think it's because some of the notes are just slightly out of sync. If I had a log, it'd be easy to go through the list, identify the beats that are out of sync and fix them.
