I have a webshop where I need to run some custom code on the Cart before it is rendered. The scenario is that a user will post some data while the Cart is showing, and I want to use this data to manipulate some values in the Cart.

Cart V1 had the notification "Dynamicweb.Notifications.eCommerce.Cart.BeforeRender" which fit my requirement quite well as I want to make sure it is always done before the Cart is rendered. But unfortunatly we are using Cart V2 which do not throw that notification. I have looked through the notifications in "Dynamicweb.Ecom7.Cart.Notifications" but I can't seem to find anyone that I can use. The closest is BeforeRenderEmptyCart, but that is not particularly useful in my situation.

So my question is in part two-fold:
Can anyone see a notification in the Cart V2 namespace that I can use?

Or failing that, is there another approach? I have some custom fields on the Order and OrderLine that I want to manipulate related to the information the user posts. I could use a custom module, but I want to be sure the code is always run before the cart is being rendered.
