Hi there, i need some help printing a packing slip - not sure if I am in right category (sorry I'm new)

I am working on the new Partner V17 which forms designers is much easier now.
I have modified the CSDOCSP's supporting document CSINDVSP to resemble a packing slip
My question is, is there a way to only print the supporting document on it's own?
As we only wish to print a packing slip on request and not together with a tax invoice.

Hope someone can suggest an alternate way.

Regards
Martin
