In my experience, using many different fields configurations ends being a mess (I guess if you do it thinking carefully, documenting, etc it can work fine)
I use JSU, but for that simple requirement there are free add-ons that can save you, i.e.
AM Utils is also not free. It has free trial. But like JSU, you need to buy the app.
JSU can configure workflows without coding and has an easy-to-use interface that eliminates tedious coding and time-consuming testing, debugging, and error-fixing. You may also easily create field conditions that won't affect other screens. Perhaps you could find out more on this link: https://confluence-apps.beecom.ch/display/JSU/JSU+Configuration+Guide
