Any way to add a custom button on Supplier Address page, which on click will update value of DFF?

The ask is we want to have an explicit 'Approve' button on Supplier Address page which when clicked by Approver will update a DFF field so that appropriate workflow can be triggered after that.

We need to have approval mechanism for each address and not just at supplier level. Challenge we face is that there is a differentiation in subsequent workflow if supplier edits an existing supplier data or if he adds a new address altogether. To keep this distinction, we have defined that DFF.
