Is it possible?

Hello

I search for a way to achieve this scenario:

Display and connect 2 custom fields in the checkout.

The first field is the doctor’s name of the customer. (let say we have 6 doctors name in the database)

The second field is for apply a specific coupon code

Each doctor is link to a specific coupon code. Both fields must match together to apply a reduction.

As exemple, if a customer enter a doctor’s name correctly, but enter a different coupon code(not the one link to this doctor’s name), the reduction code will failed.

Do you think i can achieve that with your plugin?

Thank you
