Hello @Anonymous. Create a new javascript extension, read out the array and return the sum of the quantities?

Something like this:

var productarray = utag_data["cart_product_quantity"];
var total = 0;

for (i = 0; i < productarray.length; i++)
{
  total += parseFloat(productarray[i]);
}
utag_data["total_cart_product_quantity"] = total;
