Is there any way to autopopulate a DFF based on another DFF

Summary

Is there any way to auto-populate a DFF based on another DFF? For example, a DFF on the Project Class code is opened and another one is opened on the Projects definition. If I set a value: "123" on the Project Class Code DFF, the DFF on the Project definition should auto-populate with the same value i.e "123" (insert + updates).
