Crazyhouse pocket

If I create a crazyhouse position in board editor, how do I add the pieces in pocket??

You have to add them to the FEN manually. They go after the last slash, as if there were a 0th board rank: lichess.org/analysis/crazyhouse/rnbqkbnr/ppp1pppp/8/3P4/8/8/PPPP1PPP/RNBQKBNR/QQRBNPqrbnp_b_KQkq_-_3_2

Thanks!
