Email from different address

Dear All,

We use your delivery plugin. The most popular option is DAO with an interactive map.
The problem arises when a customer creates an order and uses “Ship to a different address?” option on the checkout page.
The customer enters an email from another person in the “Ship to a different address?” form, to whom he forwards the package.
The problem is that DAO does not set that second email address, but the email address from the customer from the “Billing form”.
Is it possible to do something so that in that case DAO accepts the email address from the “Shipping to a different address form”?
