Shopify Bundles

The app is simple to use. Almost too simple. Before the complaints about reporting, why doesn't the app allow for you to create a bundle that automatically pulls the desired quantity of each item into the bundle, instead of me having to create a predetermined item with all of the components in it? Why not allow the customer to choose the bundle and even discard one or more items from the bundle that they may not need. If my customer needs 8 of the 10 different items to rebuild the instrument in service, they can select a full bundle and then uncheck the individual items they don't need. This would be my recommendation.
