Change 'Add to Cart' button based on stock levels

Hi, I'm looking for a code injection I can use to auto edit the 'Add to Cart' text.

If the product stock level is set to 'Unlimited' I'd like the button to read 'Pre-order', otherwise stay as 'Add to Cart' please can someone help?

This can be done manually per product with the Custom Button feature of the product editor.

Would this work for you need?

Of course this does work, just requires a lot of patience and monitoring. Was looking for something more automated.
