Bottleneck in collaboration messaging for electronic invoicing

Summary:

Using CMK we are delivering our invoices as XML.

The trouble we are facing is that setting up customer site or account with prefered delivery as XML is not enough.

For each customer we end up creating a Trading party setup and/or service provider.

This is extremely inefficient as each customer needs manual configuration.

Is it required that each customer need to be setup as trading partner? Is there a better way to achieve this?
