Is it possible to populate a dropdown choice field from another list? We are creating a few forms that ask for an excecutive/manager name and we would like to manage a single list instead of updating several forms when there is a position change.

From what I can gather, it's only possible with JS in classic designer. I've got limited experience with experience with JS that I'm willing to build on, but I'm feeling overwhelmed in filtering out useful direction to get started.
