How to play the same animation in two different ways?

I'm trying to make an animation possible to play in two different ways. The first one is to play animation from beginning to end without stopping The second one is an interactive way - something like slideshow made in powerpoint. My idea was to use gotoAndPlay() function with stop() function. It doesn't work the way as I expect. For instance - I've one animation made of 500 frames. It makes up some 10 slides. If I put after every 50 frames stop() function then it's impossible to play this animation from beginning to end without stopping because of stop(). How to handle this? It would be nice if there was a function to indicate to play between some frames. For example, start playing from 1 until 50, then stop. Then start playing from 52 until 100 and stop .... then from 450 to 500. Besides that from 1 to 500.
