I'd like the feature of being able to create an automatic rule to combine orders that match certain criteria. I currently do that manually and it is a headache. My customers are students who for example order 3 products: a certificate, a book and a pin. I only want to send them 2 packages instead of 3 and therefore combine the book and the pin into 1 package. I am currently doing that manually and I have over 500 orders like that per month and I think a feature that will allow me to do that will be so useful.
