Distinguishing between real orders made on website and manual subscription creation

Hi team, we are struggling with the fact that if I as an admin create a subscription in Joomla admin, an e-mail is sent as if the user bought the subscription at our website. Our sales team is then confused and have no idea whether the payment is real or not. Is there any way to distinguish these e-mail notifications? I am ofc talking about custom programming for us. Anything: in-line CSS in the email, adding a class in the email, changing email title, not sending the e-mail at all.... anything. My ideas is to click a checkbox in Payplans admin to distinguish a real payment from a manual one. Thanks a lot.
