I've just bought the Vegas + DVD bundle and was wondering...

Is it possible to burn a DVD with menus, clips, and all, and then at a future time to be able to continue editing the information on the DVD? For example DVD Architect leaving some special code on the DVD so that it can be copied and continued to be worked on and then re-burned. If it doesn't have this feature, I think that is a fantastic one to include.

I know that some Sonic Solutions products have that feature and that their upcoming DVDiT! program will too.
