I wish I had a way to filter collections for products that are 'available to be purchased'

Shopify does have a filter "Inventory level (> 0)" but when using other Mechanic tasks like "Reset inventory levels daily" or "Reset negative inventory levels to zero in bulk" to handle perishable products, I'd end up either with products being displayed in the collection while being 'out of stock' or wrongly filtered out.

What I'd like is to only include those products (via a tag? metafield?) in an automated collection that are available to be purchased - in other words: either they have a positive inventory OR they have inventory policy set to "CONTINUE"
