How can I partially fulfill pick up orders on my online store?

No we have not found a suitable APP to do this. We are still relying on tags, adding notes to orders and using an EXPORT to keep track of each line item. It is very tedious and a shame that a company of shopify’s status dropped the ball on such an integral part of order fulfilment, especially at times like these when goods and services are taking longer to produce/ship.
