When I'm editing multiple files in a sequence, I want to be able to add a flag or pin to a moment of one file (i.e. when I clap to create an audio sync in audio file 1) and then be able to set a flag or pin in another file (i.e. the clap audio sync in video file 2), so that when I'm working with 3+ files in a sequence, I can quickly identify the sync moment to align the files.

Today I have to continuously scroll in and out to try and find the sync point in the various files, and in doing so will often lose one or take more time.
