Edit Processing Time of product / Cart / Order

[JR97]

Hello,

we are a merchant and offer a wide portofolio of products. Sometimes products are sold out, but we reorder them instantly or they are already ordered

If we use "Expected Delivery Dates", but it totally ignores the fact that stock is negative. 

I would like to use this feature and i.e. use a metafield on variant level to set the procurement days for the case that the product is out of stock. This value should be added to the delivery time and help the customer to know when to expect his package.

This could be done by a custom function or app.

Problem: There is no endpoint to "processing_time" or similar.

I checked the API documentation for order, cart and product
