@synsanken That’s ok, I’ve marked it as resolved. It’s also good to keep it here in case anyone else also thinks the same and comes across this thread.
You’ll want to add the change in an MU plugin. This can easily be created by just creating a .php file inside of the wp-content/mu-plugins directory.
We have a set of instructions up on the Primer theme documentation site on how to create an MU plugin for customizations such as this.
https://godaddy.github.io/wp-primer-theme/tutorials-and-examples/tutorials/mu-plugin.html
With an MU plugin, none of your customizations will be wiped out with a theme or plugin update. If you add it to your themes functions.php file, then yes this is something that will need to be re-added each theme update, which is why we recommend an MU plugin.
