Can't edit orders in different currencies on Shopify Plus: what's the solution?

I recently found out that editing orders in multiple currencies is not possible. This is a problem for multiple markets in shopify plus. For example if I get a short shipment, and want to remove an item, change a size ,etc - its now impossible. I feel like that is a recent change?? What would happen on Markets Pro if thats the case now?

in the FAQ SECTION:

This is super frustrating for us, too. We don’t want to have to cancel every international order because a customer wants a different size. Also curious if Markets Pro would help but I don’t think it will?

Hi @rfrench and @amandaatremix

I am not sure Market Pro would fix that; let me ask if you could encourage international customers to get in touch before they order so you can confirm the stock, etc. would that be of help?

Kind regards
