Quiz feature idea: time-modulating answers?

Sorry for the back-to-back posts, but I had another feature idea for quizmaking: the option to assign additional time values to correct answers. Say one wanted to make a quiz where the questions get progressively harder to answer, but still wants to keep the player on their toes for the easy questions. They would put in a base starting time of maybe 20 seconds just like how one normally enters the regular time limit on a quiz. Then they can assign +3 seconds to the first answer, then maybe +5 seconds for the next answer, +10 for the next, etc. This way they can keep all the answers fast-paced without having to come up with some optimal time and fine-tune it with player input. Another use would be a Jeopardy-type quiz where you can use the yellow box to answer easier questions, but they don’t give you as much time, so it’s beneficial to know the answers to some of the harder questions to win yourself more thinking time.

The time values wouldn’t affect point scoring, but it could be a new feature to help make quizzes more dynamic. Thoughts?
