Is there a way we can default the value from a DFF to a standard field value on assignment page

Summary:

We have a requirement to default the Standard "Notice Period" field on the Assignment page based on the value populated in a Descriptive Flex field (DFF) on the same page.

We are exploring the possibility of achieving this using Visual Builder Studio (VBCS). Could anyone please suggest the best approach or steps to implement this requirement? Specifically:

• Can we capture the DFF value in real-time and use it to populate the Standard Notice Period field dynamically?
• Are there any known limitations or prerequisites we should be aware of?

Any insights, sample code snippets, or references would be greatly appreciated.
