howTo ensure that the project class code value in one category matches the value in anothercategory?

Summary:

Is it possible to match the values of two class categories?
For example, if the Project Complexity class code is set to “Low,” the Review Regime class code should automatically be “Low.”

I tried using Sandbox Page Composer, but it seems this is not possible since the field object refers to column names rather than individual categories
