Need ability to require cosignature in order to sign orders

Our facility requires advanced practice providers (APP) to submit any orders they place to a physician for cosignature. While we can make a cosigner required, the system still allows the APP to place the orders without making a cosigner selection, and this sends the orders to our 999999 provider number. It would be wonderful if the system would 1) force the user to select a cosigner before allowing signing of orders and 2) not allow orders to go to the 999999 provider for live patients.
