Scheduler batch template, change from address dynamically

We currently send a burst email report to our vendors with the email body stating "please reply by email to buyer@mycompany.com" (with the buyer's email being dynamically populated based on the vendor using =NL("First","Salesperson/Purchaser","E-Mail")) . However as we send via SMTP the From Email address is a generic email address. Some vendors then reply to the generic email address. It there a /F option or similar within the autopilot to enable us to dynamically change the From Email to the NL function as above?

Alternatively, is there a way to change the Delivery Options of the sent email to "have replies sent to buyer@mycompany.com".

Many thanks for any assistance
