How long do you want the clips to be? You can do this in Prelude pretty quickly, but not in one step.
And you’re constrained by having to set subclip markers in 1 second increments.
Say you want two second shots. 30 frames before the mark and 30 frames after. Set up your subclip marker for a 1 second duration. Find the frame you want, mark the subclip (tap 1 and enter description) and repeat for all your decisions. Then go to the Marker List and highlight the in point display for each clip and paste -30. This actually isn’t that cumbersome.
Right click on the Timecode window display to change the display to frames if that helps. Also, not a bad idea to make a Marker Template with a custom name so you can just number your clips instead of having to fully rename them.
