Product Bundles for WooCommerce

The Bundle Sells in Linked Products for Simple Products should have quantity management.

At present a user can only add 1 (with a checkbox).

If the bundled product is granted a discount, the user can then edit the cart for multiple products, and get the discount on all of them (irrespective of the number of primary products they bought).

e.g.
Add 1 primary product
With checkbox ticked for bundled product at 20% discount.
Then
Edit the cart to 100 bundled products, all of which get 20% discount.

This should be constrained to the number of primary products, or managed by the Linked Products to set a quantity with maximum / minimum
