On my website, I link to a scheduling page from different places, and I'm thinking of using custom fields to add that URL and then pull it up as a dynamic data in Oxygen. This way, if the link changes, I only need to change it from one place.
Is what I'm doing the most efficient way of solving this issue?
I do not have your whole scenario but if you get the URL from one place (not like posts), you can use the extension MB Settings Page. It works like the theme options. https://docs.metabox.io/extensions/mb-settings-page/
.
