Until you receive a PCN with your name and address on it, you have no role or standing in the enforcement process.
What do VW Finance do when they receive PCNs for cars they have leased out to customers ? Under the law, the registered keeper has responsibility for payment or for appealing a PCN. Hire and lease companies can submit representations stating they are a hire company, and provide the hirers name and address. The first PCN is then cancelled, and a new one served to the provided name and address.
