How to designate email accounts

Hello under the email settings, I see that there are three type of email accounts. General Contact, Sales Rep and Customer service. I see that I can also set the default email address to be used. Is there a way that I can set certain email accounts for certain actions. If the contact us form is used that the email goes to customer service, but if a sale is completed the email receipt and anything having to do with the order all come from the sales rep email account.

Thanks

go to admin area under under content management tab select message templates. you see the list of message templates for every actions. choose your  templates and click edit. then in the bottom of the edit template change the email account.
thats it.
