[Feature] Show option to enter billing address for stored cards.

[kesavaj]

Is your feature request related to a problem? Please describe.
At the moment we don't see any option to capture address while using a stored card. If the user has changed address, then we don't have option to ask the user for new address. Also if we haven't captured the address while storing the card, then there is no way to capture it now

Describe the solution you'd like
A clear and concise description of what you want to happen.
Provide option in the stored card configuration to allow us to capture billing address and show the address form if that option is selected.

Describe alternatives you've considered
The only alternative is to ask the user to remove the stored card and add again, which is a hassle and not a good UX

Hey @kesavaj

Thank you for reaching out and for your feature request!
Indeed, we are planning to add more "End-to-end Checkout" functionality to our SDK, and it is nice to see an actual demand!
Your request will help us to prioritize 2022 OKRs better!

I am afraid that the Billing address on the card component was not initially intended for merchants to collect address information.
It is not validated by any means, and we are only using it on v4 for 3DS / fraud checks.

Currently, I can only suggest creating a custom address form in your app to collect the shopper's billing address information.
You can use our resources or any other popular form builder.

BTW, in v4.2.0, we will add a PrefilledShopperInformation that you can use to populate all shopper information to a DropIn / Components.
