Trade in

Hello, I recently bought a iPad Pro 2020 11in several months ago during the time of COVID-19 for medical school and have found it very useful! Unfortunately after using it for sometime I find the screen size difference compared to the 12.9in version a lot more convenient for how I am using it. Is there an option for me to trade the 11in and replace it with 12.9in and pay the 200$ difference rather than trading it in and buying it over paying more money?

thanks!
