Is it possible for a customized item added to the shopping cart to be edited?

I will attach a video.

To explain it, once a customer makes their product selection and completes the customization fields and then adds the customized item to their shopping cart, if they go back the product is blank and all customization is missing. So, when they’re reviewing their order if they realize they had a typo or need to make a change they cannot return to edit it, they have to completely remove the product and do it all again – or email us.

This is not what I was meaning. I have the variable product set up okay.

The problem that I am having is that once a customer selects their item and completes the personalization field, they add the item to the cart. Once they are on the cart page, if they want to edit their entries they cannot do so. When they click on the item (from their cart) they are taken back to the product page and all the customization fields are blank again. If they wanted to order additional, like items with different customization that would be perfect, but I’m trying to figure out how they can make edits to the item(s) in their cart.
