Separate billing email address for business purchases

I'm getting some purchases and quote requests from schools/music departments.

Usually those purchases are handled by a department or central office, after a formal quote is proposed. However, sometimes the checkout email entered can be a generic or departmental address, which can make license delivery and follow-up confusing for the actual end user.

A possible improvement would be to allow buyers to specify a separate “license delivery” or “software contact” email address at checkout (when doing a business purchase), distinct from the billing or business email.

This would help ensure the license reaches the correct person while keeping billing details unchanged.
