Product Bundles for WooCommerce

There are times where you want to have a bundle that is partially customized by the customer and partially not. For example a cooler (which is an inventoried product and not customized), 2 coozies (which is an inventoried product and customized), and 4 snacks of the customers choice. Right now to do that you would add the cooler and coozies to the bundle with a set number and either hide or make visible and then the customer selectable items. You need to set the max products to 7 to allow for the 4 choices but then the verbiage is Please pick 7 3 are already chosen. That is confusing.
Please provide a way for a bundle (that you track all of the products for inventory) can have preset and customized pieces.
