possible to get custom attribute dropdown like Size on Cart page?

So I added a "Pot Size" attribute to my plant product (1gallon,3gallon,5gallon sizes in a select dropdown list).
That field got added to the Variation (since its different per variation).
Now i can set each Variation's size for my 'Plant Product' type and dynamically on the product view, i can see the price/title change.

That field btw has "enable this field to function as an attribute on Add to Cart forms" checked for the "Attribute Field Settings" which Im guessing is what makes that dynamic price/title change work when changing the dropdown (aka the "Add to Cart" form).

I was wondering could that attribute also show up on the 'view cart' page (in the same nice way the 'product view' page changes the price/etc when you change the dropdown via AJAX [which is good for caching])?

Right now, I can only add the text via adding the "Pot Size" field on the "Product in Cart" view (on the page admin/commerce/config/product-variation-types/product-plant/display). But this only adds read-only text, and not a full dropdown-ajax functionality where you can update the size of the product you want straight from the View Cart page.
Is this possible without too much custom code (I just thought maybe someone has done this before so it would be built somehow into Drupal Commerce's Cart form)?
