Finding the same timecode position on a synched clip from the unsynched original

I got both clips in the browser.
By mistake a marked my favourites in the unsynched clip.
Before removing the unsynched clip I want to copy my favorites to the synched clip.
Can this be done?
I can redo this but if there is a way to salvage my favorites then good.
Otherwise well...lesson learned...look at the clip twice!

I believe this is the same situation as accidentally marking single-cam parent clips of a multicam, then editing those single-cam clips into a timeline, then realizing you wanted the equivalent ranges from the multicam. For this reason it's wise to use multicam not sync clips, then immediately reject all parent clips of the multicam and run the Browser filter in "hide rejected".

The only procedure I know to fix this is matching frames and doing replace edits, clip by clip. See this post for details: www.fcp.co/forum/4-final-cut-pro-x-fcpx/...meline-in-fcp#107294

Thank you.
Just a few clips so it will be quicker to just redo those.
