Nick here from Shopify. Great question!
This is something which can be customized into your store's theme, but it does take a bit of coding in order to make it happen. To get to that section of your theme, from your Shopify admin, click:
Online Store> Themes> Actions> Edit Code.
Once there, unless you are comfortable making the code changes yourself, it could be worth your while to look into hiring a Shopify Expert to make the changes for you. I'm not an expert in coding by any means and wouldn't feel comfortable offering that information or know what to do. You can see the Expert directory here and find someone you resonate with for this task.
Hope this helps!
I wouldn't be able to give any code advice, I wouldn't be comfortable to do that with my skill levels. However I did find a community topic from a couple of years ago with some code in it which could point you in the right direction. You can see it here.
If for any reason you make a mistake and need to go back on some code you edited, you can do so by rolling back to an older version of your theme. There's a help guide on how to do that here.
