A easy approach would be:
1) Use the Solid Color generator to make a slug .5 seconds long on a new layer above what you want to cut up.
2) Make this slug into a Compound Clip. Call it “SLUG”
3) Hold down F11 to overwrite this new compound clip from the media pool onto the new layer to create a long string of slugs the length of your timeline.
4) With Autotrack Selector enabled for the layers you wish to chop up and the new layer, press the down arrow followed by the keyboard shortcut for Razor (Command B). Repeat this until you reach the end of the timeline.
5) Alternately, you could export an EDL from the new SLUG layer and use the previously mentioned Preconform method.
Personally, I have written Python scripts to do this inside of BBEdit. If this is your chosen career, I would seriously look into BBEdit and the use of Text Filters for all sorts of time saving ways of manipulating EDLs. Perhaps ChatGPT can write the Python code for you? 🙂
