Waitlist feature

options for customers to preorder items (not a notify when in stock), without paying until the item arrives and is placed in their cart. Almost more of a waitlist for specific styles/sizes. We want to have this information on the back end, to place orders based on interest in specific styles/sizes. The feature new are hoping to find is such, that. customers. can see. items they are waiting for and will purchase when they arrive. And we can see a list of these items that customers are waiting for.
