Would like to be able to preset facts – Math Quiz Lite : Add Subtract Multiply & Divide Review

This is a great spin on memorizing facts. It would be a great alternative to flash card practice if I could narrow it down to the facts he's being quizzed on. For example, being able to turn on just the +1's, etc.
