Hello, drtyres. I can certainly see how Price Rules would be a great addition to your workflow. Currently, Intuit hasn't release date for when this will be officially available in Ireland. It is still in the Beta pace, so only selected customers can turn it on. Please also know that this option isn't available in QuickBooks Online Simple Start or QuickBooks Online Essentials.
For now, I encourage you to share your request with our product engineers directly so they can consider this in a future update.
