Yes, even though it's in indeed in Symfony docs, I am not sure every PrestaShop developer knows about it. So I thought that we should document an example of what you can do with Symfony events, especially when looking to customize part of the BO behavior.

It would be a new entry in https://devdocs.prestashop.com/1.7/modules/concepts/symfony/https://devdocs.prestashop.com/1.7/modules/concepts/symfony/
