Specific emails used for orders.

Hi DEAR support,

Kindly note it would be great to have the following feature request. Which is to have a specific mail address to isolate one email off to just purchase orders - I can see we can select company billing email or logged-in user; however, if I create a purchase order, I don't want purchase order emails to be sent to my personal email.
 The same with the user with the purchasing email on it; if they create a sales order and send an email out, we don't want any replies coming into the purchasing email inbox. 

Thanks in advance!
