Modification / addon Prestashop

We want to be able to toggle the visibility of products based upon a link between the manufacturer and customer groups. Example: Group 1: Customer 1, 2 and 3 Group 2: Customer 4 and 5 Manufacturer A: product A1, A2 Manufacturer B: product B1, B2 Manufacturer A is visible for Group 1 and 2 Manufacturer B is visible for Group 1 On the site if a customer 2 logs in he should see products A1, A2, B1 and B2 if customer 4 logs in he should only see A1 and A2 Toggling should be done in the manufacturer tab Compatible with Prestashop 1.5.5 / Preferably as addon module.
