Customer Phone Numbers on Shipping Labels

Hi,

This seems like a straight forward issue but I can’t seem to locate a clear answer and would appreciate any feedback.

Because we ship internationally and because some orders are quite large - the carrier often needs to call the customer directly. How can we have customer numbers entered at checkout automatically add to the shipping label?

Seems like a basic business issue but I can’t find a solution anywhere.

Thanks!
