How to tag custom item orders in POS sales?

[JHBuffaloMeatCo]

Hi there,

I'm looking to tag any orders that contain "Custom Items" that were typed in manually, usually during a POS sale or sale from a Draft Order. The second line under the product title says "_shopify_item_type:custom_sale" 

Thank you!

I think that _shopify_item_type field is an order / lineItems / customAttributes. And that is the key, with custom_sale being the value. So you could try checking that key and value in a condition.
