You can do this already. My order notifications, invoices, and drive-thru notices
are all self-formatting for domestic/international, form of payment, form of
shipping, tracked/insured, etc. It takes a LOT of work to create it, but everything
is much faster after that.

back to the point where something is done with the suggestions. But I do see
some development on BrickLink right now.
