I've had a few customers request additional items for an open order, but since it's not possible to do that, I've either had to cancel the order and have them start all over, or I've set up a listing on the regular Etsy site that has the additional items they wanted, so it's a 2 part order that ships together. Neither solution is super professional, but maybe others here have better ideas on how to handle this?

Hi Sarah,
Thanks for getting in touch about this. We understand this is a limitation in our order system. We will be working on giving sellers more flexibility in the future, including the ability to add new products to an open order before it has been invoiced. Currently, the buyer would have to submit an additional PO with the new items. We apologize for the inconvenience!
