Streamline theme provides a template where the button says PREORDER instead of SOLD OUT, which is great.
However we would like both buttons to show. So that the SOLD OUT shows and underneath SOLD OUT it says PREORDER which prompts to checkout. Can someone advise how to do so?
NOTE: When stock is 0 it says sold out, when stock is valued it says Pre-order instead. We want stock to say 0 and buttons to say sold out and underneath pre-order.
