How do i use my guest list to see how many invitations to order based on household?

I'm really frustrated with the guest list mechanic on this site. I kind of regret going through all the painstaking effort of connecting ALL of our household groups with that little chain icon. Because there seems to be NO WAY to export all of those hours of work to the invitations!!! How hard is it to make a number of households to tell us how many invitations to order?! This is ridiculous! What is the point of entering all of this information if I can't use it to order invitations and have to do it all over again?! Ah! I should have just skipped doing it here and saved myself the trouble.
