Add a second, fastening, button (French Bearer button) to the pants

Please add a French Bearer button to the pants (at least chinos), for additional functional fastening so the pants.

A French bearer is a button at the closure of a pair of trousers in addition to the usual front button. It is inserted on the inside of the trousers, usually behind or to the side of the fly opening.

This extra fastening holds the front of a pair of trousers flat, which helps to keep them looking crisp and smart.
