Easy way to stretch 2 blended songs in Audition 2.0?

So if i have 2 songs i want to blend together and one version is SLIGHTLY faster than the other, at first they will play fine then 20 seconds later u can tell its a little off-beat, i have a theory on how to fix it but not sure how to do it in Audition or even if u can...

What i would do is set a marker at the exact beginning of the first word of the first verse, then set a marker at the last word of the last verse or somethin. in multitrack, line the first markers up then obviously the 2nd markers will be off, is there a way for Audition to automatically 'equalize' those 2 markers and stretch it precisely?

Thanks in advance
