How to map DFF created at Job to a DFF at position level?

Summary:

I need help in mapping a DFF created at job level to the position level.

Content (required):

When we select a job at position page, it should show and auto-populate the DFF which was created at Job's page along with the value entered in that page as well. I created DFFs at both position page and job page with same name. Could someone help me on this please?
