Bulk Add & Edit Products in Bundles
Instead of having to individually search for each product offered in a bundle, allow bulk addition of products ("select all", select by category, etc). Also allow a bulk edit of each product's options in a bundle, so you can set all products to have the same values for min-quantity, max-quantity, optional, etc.
