Fleurelle Flower Farm review for Mergify: Combine, Merge Orders

I really do love this app however, I've come across a couple issues. It would be great if only the full name and address had to match. For some reason if a customer purchases with the same name and address but uses a different email, Mergify doesn't catch those orders so they get missed. I also offer several pre-ordering sales in the summer that are all shipped in the fall, so customers can combine those orders to ship together. For some reason, the Mergify app doesn't catch all orders under a customer so I am shipping separately and losing money since they only pay for shipping on one order (by using a code). I'm not exactly sure why some orders get merged, and not others but I merge all orders until Mergify has no more suggestions to offer. I already have this set to the last 360 days so I'm unsure why this is happening! The last request I have is that instead of sending a custom email saying that orders # and # have been combined, it would be best if the new merged order with the confirmation number was sent to the customer instead. This way if they reach us with questions, they have their new order number. I will update my review if/when these changes are made!
