How to start a Background Image video on a frame other than 1

I would like to import a video as a background image, but it appears that all videos always start on frame 1 on Blender’s timeline. Is there a way to start video playback on, say, frame 90?

(I saw this add-on… https://blenderartists.org/forum/showthread.php?411178-AddOn-Background-Image-Setting-to-Frame …but I couldn’t get it to work with videos.)
