If you select everything on the timeline you can shift it all to the right. Make sure everything is orange in the timeline area before you move it all. Then you can add your symbol at the beginnig. You might need to turn off everything you just move a 0 and then on when you want the rest to appear.
I will definitely give it another shot. I tried that, but I think I might've given up too easily . I'll let you know how it works out.
Hey, it worked out fine today! I don't know if I was sleep-deprived or otherwise confused, but it's all working just as I had hoped. Thanks!
Wonderful ! Good luck on your project.
