Seek Bar Rewinding

Is there any way to configure the seek bar to allow a rewind before completion, but not allow them to move past the seek bar point they rewound from?

For example, a user is listening to a training. They have not yet completed the training, but they want to stop and hear a part they missed again. I know the options are not in the player settings. The only thing close is to allow drag after completion. This would be more along the lines of allowing seek rewind functionality, even before it completed.
