How to Mass update DFF in Discount Rules

Summary:

Hi Team,

Our Requirement is to bulk update DFF in Discount Rule. We have various Simple and Attribute based Discount rules across various Discount lists. We need to update a certain DFF value across all the discount list in each of the discount rules.

What is the best possible way to bulk update this ?

1. Can we update this using Adfdi ?
2. Can we update it using FBDI ?

Kindly do let me know if any other details are needed from my end.

Thanks,

Ravi
