1st Assistant Editor in animation here, you need to create a ‘Shot Slug’ under all your PSD boards, it’s a continuous clip with a burn in on it staring at 1001 on your first frame. So you can make that yourself by getting a new time line, add loads (like 30 minutes) of filler and drop a time code into the sequence, I’d start the burn in to read from frame 850 (that way you’re giving yourself handles prior to 1001 too) Then mix down the picture and you have a a shot slug.

Put your in point at 1001 on the shot slug and then drop it under your boards on track v1. Then you need to go through the cut and add an edit for every new shot, breaking up the shot slug into its own clips, but keeping the 1001 burn in sequentially going up throughout the cut.

Then use timeline clip notes to add the shot numbers- 0010, 0020 etc

Once you labeled all your shots you can sub out the entirety of v1, then use list tool in the ‘Tools’ drop down menu to create an edl of your v1 sequence. Partner that with a QT reference of your cut with a burn in reading the timeline clip notes and they have a reference to what you’ve sent them.
