Reply to Beatgridding a Live Mix in Ableton

I am using a set up with 4 traktor decks routed into ableton to record a mix and i have finished recording but the issue i am having is that i did not sync ableton to traktor when recording so now that i am trying to edit my mix in ableton the bpm changes are not recorded. What i am looking for is a better way to beat grid my mix than finding the bpms at points in the mix and penciling them in. Is there any way to automate the bpm while tapping along to the mix?? Thanks in advance
