What Jeremy suggests is that you don’t have common timecode, and have to sync trough PluralEyes.
But, you do have commont timecode, so you can merge in the bin if you like, just sort on TCin, select matching pairs and do a merge on TC.
If the cams have rolled for a long time, it’s doable by hand.
(half hour of tedious work will get you there)
However, BWF files might be problematic with FCP.
check https://www.spherico.com for some in depth info on FCP & BWF.
But if there are tons of clips,
an option is to use my BWF /QT merge application.
(it comes with the FCPauxTC reader, download a demo from my site).
This thing can paste the BWF’s into the QT’s.
Do so before editing, as when the track amount changes, FCP won’t relink.
Another gotcha is NOT to merge dual mono and stereo files.
It works swell, but you won’t be able to media manage.
(the sound guy can split poly BWF’s into multi for you)
Or, use Intelligent Assistents Sync ‘n Link.
