[F8] Controlling movie clips (using actionscript 1.0)

Hello, i am currently working on a presentation involving many frames, each with its own multi-step movie clip, and am having some difficulty with the navigation interface. Is there any way to
1. Make it so that pressing the back button will load the previous frame with the contained movie clip starting at its last frame?

2. If i am using a contained movie clip to make the parent movie clip to play backwards, is there any good way of still making it stop on frames with a stop action?

Any help would be greatly appreciated.
