I think it`s better to try just warping and then grabbing a beat right near the end, adding a marker and shifting it in.
If you can`t get it, then try the quantise. The quantise isn`t always your best bet for stuff with awkward beats, or stuff where the kick and bass share similar energy, or stuff taken from vinyl as sometimes it gets the transients wrong, or slightly off..
Mostly it works ok though.
