change sender when emailing invoice and product description on paypal cart

change sender when emailing invoice and product description on paypal cart

When I email an invoice, the From/Sender shows my name.  Can that be changed to my company name instead?

When a customer clicks the "pay online now" link in the emailed invoice, the paypal cart's product description shows my name as well.  Can that be changed to display my company's initials and then the invoice number?
