Hello, 

Our company is new to Odoo (version 17)  and we wanted to be able to automatically add a free 1 year warranty as a service to the cart when certain products are added to the cart as a means of demonstrating to the consumer that they receive that and have less abandoned carts and so they also understand the service. However, we cannot find a function to do this or any means of customizing the cart without the customer manually adding the "automatic" one year warranty upon purchase. Is there a way to do this without mods as I heard that they can be buggy. 

Thanks!
