Different Reward Tiers

Can you make it such that I can provide one type of reward for a written testimonial, and a second upgraded type of reward for a video testimonial?

Currently, if I’m providing rewards for video testimonials, then I can’t provide a reward for a written testimonial.

Or if I’m providing a reward for a written testimonial, then the same reward is given for video testimonials.

I want to give rewards to anyone who gives a testimonial, but I want different rewards for video versus written testimonials.
