I wonder if it is somehow possible to query the number of existing orders of a merchant? Of course one could query "get all orders of merchant 123" and check for the number of items in the array, but as soon as the hard limit of 1000 is reached it gets a bit tedious working with offset. I am sure some merchants have 100k or even more orders in the cloud. Would be good to get just a number of existing orders back! (same is true for items / payments / cash events etc.)
