I appreciate your response. But I figure out how to get out on my own. In fact, I've set up and taken several consumable IAPs off the market. I therefore believed that I needed to re-attach the new subscriptions to the next binary build. However, it turns out that if your app was published before, all you have to do is get the new subscriptions' metadata ready and submit it to review. Your binary build will function automatically without requiring you to reattach it after it is approved (in the Distribution section). Ref: Submit an in-app purchase
