Product bundles - Splitting amongst Variants

Product bundle feature could be improved - at the moment if your product has variants there is no way to split them out to have product bundle variants at different prices. The product bundle weight also isn't automatically calculated from the individual products, which should be an easy yet very useful thing to incorporate. It would also be hugely useful to allow more than 5 products, which isn't enough for some of the bundles I would like to offer. Fantastic idea and I would love to make use of it, but can't at the moment with it's current functionality.
