Navigate directly to particular elapsed time into movie using iMovie?

I have video of my son's sports games. During each game, when he makes a good play, I note the elapsed time (like 3:17, or 3 minutes 17 seconds in).

Later, once I've transferred the videos from the iPad back to my Mac, I want to navigate directly to that instant without scrolling . I just want to say to iMovie, "go to 3:17".

How can I do that?

TIA, Matthew
