I'm Ann, from the team here at Shopify :)
You can likely get this done with the help of an app! Apps are like extra features you can add to your store. In this case, there are a few apps in our App Store that will let you set up specific rules surrounding orders. Check out these:
Check those out and see if they help! It's good to note that these are all third party apps. This means that they weren't created by Shopify so if you had any questions about them, or needed a hand with setting up them, talking to their support team directly will be the best bet. You can see their support teams contact information on the apps page directly.
I hope this helps! If you have any more questions or concerns feel free to reach out to us on this thread :)
Have a great one,
