Video backgrounds continue after changing?

Hi I just got DeskScape and think the idea is really cool, I was wondering however if it was possible to make it so a video background could pause after changing into a new video or new picture.

Like say I have my backgrounds set to change every 30 seconds. I choose to have a 5 minute video as my background. After the 30 seconds it shifts to either a different video or a still image and then back to the original 5 minute. Now normally, or at least with what I've seen so far, after the video background changes it restarts the video. I'd like it to pause the video from where it last stopped and continue on from that point until the next time it changes.
