Hi. my stock changes daily and it would be impossible to keep it completley up to date so i want to be able to change the link on the built in anchor of the add to cart button so that when you click on the buy now butrton it links to the to call a number link.For example i have product page Washing machines and a product cataloge setup with a list of products but they will quite often be out of stock the day after but i dont have the time to update daily so i want to add a call now button instead of buy now.  i have already changed the text tag to call now on the button itself in the language options, i need this so that when i make the button visible in the product cataloge it is automatically done from within because you cannot place a button within a product cataloge card. a link to the site is below.
