Hi Lars,
As far as I know, the button calls for a method "CreateShippingDocuments" that resides in the Shipping Provider code.
I believe that currently, it is connected to the Shipping methods supported by DW and each shipping provider has its own rules for generating the documents.
For custom ShippingProviders, you have to modify the above mentioned method to follow your ShippingProvider documentation.
I don't have a lot of coding specific information since this is usually handled by one of my coleagues. This is my non-developer understanding about how this works. Maybe someone from DW can give you more details about how to tweak it or expand it as a functionality.
