Only BIG STINKY MEANIES ignore this and don't upvote.
Crazy thought. What's the point of creating a reusable custom product if the product image has to be found and uploaded manually every single time it’s quoted?
The catalog saves a handful of fields while leaving one of the most time-consuming parts completely manual. Let us upload an image to the catalog entry once and have it automatically populate on every quote (like an actual product catalog!!).
The product is already saved. It knows what it is. Please allow it to know what it looks like.
