Hello,
So far from, I think that it's possible, but can you elaborate a little more in order to better understand the purpose and the context.
But we can already invite you to check in your custom field the "display limited to", with this you can condition the display of a custom field from another custom field value :
Provide elements like relative screenshot settings, url link to the page where you want to use this button and the custom field.
Awaiting your elements in order to go more far on your subject.
Regards
