Trying to load a specific frame within a movie using 'loadmovie'

is there a way with the loadmovie function that you can load a specific frame within the movie instead of starting at frame1?

what ive been using is:-

on (release) {
loadMovie(“mymovie.swf”, 1);
}

but this starts ‘mymovie’ at frame1, is there a way to get it to load the movie and start at frame 20??

thanks
