title: Update/Remove cart attributes in Shopify
body: <p>I am using cart attributes to add extra information for each product to the cart (from the product page). <em>I am specifically using <strong>cart attributes</strong> over <strong>line item properties</strong> because the client needs to be able to edit this information in the order later on which line item properties don't allow</em>. </p>
  
  <p>Adding the information works just fine, the problem comes in when a customer decides to remove an item from the cart because although the item is removed, the cart attribute remains since it is not specifically tied to the product (other than a naming convention that we give it.)</p>
  
  <p>So, is there a way to update/remove specific cart attributes?</p>
  
  <p>Thanks in advance for your replies!</p>
