Custom Puzzles??

I want to set up custom puzzles with all the opening lines I plan to play and I want to be able to be quizzed on just these positions over and over so I can learn them. Some of them may not be technically the optimized move so I don't want something that's already been set up for specific openings. I'm looking for somewhere I could put in a bunch of lines and it would quiz me on what the next move should be at any point on any of the lines. Does anyone know of a site or app that allows this? I don't see anything on chess.com like this.

For example, I am trying to learn the French defense and watched this set of videos: Why Simon Loves The French

I would like to go through and put all of his suggestions into an app/site and have it quiz me on what the next move should be so I can fully learn all the varieties.

Thanks.

If anyone is interested in something similar someone told me about chesstempo.com that has this.
