Requesting additional feature on the EDD that allows merchants to set a specific processing time for a collection of product variants.

Currently, processing time can only be set for general product collections. However, different variants may come from different inventory locations and therefore have different processing times. Because of this, merchants cannot simply set a processing time for the entire product collection, as not all variants within the collection have the same processing time.

Therefore, merchants need the ability to set a specific processing time for a selected group of product variants.
