Regarding the Country Specific Family Data Configuration

Hi Experts ,

I have a requirement where i have to do the country specific Family Data Configuration.

We are on Ehp5 and using the WDA application

We need to add some fields that are a part of structure and add some new  fields on the Family Data screen .

However i want to keep the standard SAP screen.

Kindly guide what is  the best posible solution to the problem.

Thanks in Advance .
