Lichess study of your blunders

A recent ChessWithAkeem video gave me this idea but I want to do it using the lichess study feature if possible. He says from his games if he makes a blunder or mistake, he takes a screenshot, then at the end of the week he goes back through and flips through them flashcard style to find the right move, sort of like puzzles from his own games.

I want to do the same thing using study. I know how to make a study and a chapter and to import either a FEN or a PGN. BUt I want it to be 'frozen' at the move in the game like if the blunder was move 16, it should be on move 16, so when I go to that chapter I can try to guess what the better move would have been for me.

Thanks in advance!
