No - it would one 'to' address label and one 'from' address label printed on demand. Some suppliers get sent to on a regular basis but others only two or three times a year.

No example at this stage as it's only a conceptual idea at this stage, although if it proves doable then I will look to incorporate it into an existing project in order to have a 'one stop shop'.

Can mock an example up if you think it might explain things a bit better?
