Send purchasers Email to Business Central sales header with order

Right now we have to find the confirmation email of the order sent from the website, and copy and paste the email address of the online purchaser into BC.

It would be good if the Contact Name and Email of the person posting the order via the website would be dragged into the Contact and Email fields of the SO header in BC.

When the email field is populated in particular this then passes through BC as we post the order (ship and invoice) - allowing BC to automatically send the invoice docs etc. via email to the purchaser without any intervention/additional input from our team.
