DVD Studio Pro 4 Dual Layer Disc Question - Can Files Be Moved from Top to Bottom Layer?

HI Everyone -

I have authored a dual layer DVD for a feature film with lots of bonus material. I put the layer break in the least intrusive spot where the frame is already still and there is little sound. Layer switch is fine. DVD plays as it should with no problems other than the expected pause during the layer break.

I'd like to have the layer break at a point much earlier in the movie, where it actually goes to black and silence for a moment - a spot DVDSP4 won't let me assign a layer break marker to. I do understand why.

DVD Studio Pro has the movie on the bottom layer of the DVD, I assume because that is the first track I created.

At this point, is it at all possible to move the tracks around where the bonus features take up most of the bottom layer so the less of the movie is on the bottom layer and I can move that layer break up (without completely re-authoring)?

Thank you for your time.
