Adding barcode scanned food to recipe

When creating a custom recipe, sometimes I need to use the bar code scanner to add an item. It invariably brings only the individual serving as the amount I can enter. Since it's a recipe, I most often need more than that and have to do unnecessary calculations to get to the amount required. Since it's a bar code, can't all the data be brought in, from the entire container down to individual serving?

For example yesterday I entered 14.66 servings of BBQ sauce because the full bottle wasn't an option 🤦‍♀️
