Dynamic CMS text in Link Settings URL?

On CMS detail pages I’ve created some very simple social sharing buttons (an image inside a link block, based on https://webflow.com/website/share-button). Currently I can add links to those link blocks through the link settings. These would be sharing URLs (e.g. https://twitter.com/home?status=[Tweet text] or Error).

But [Tweet text] or [Page-URL] are generic links or text and not dynamic based on the specific CMS item.

Is there a way to add CMS field content in that URL field to make it dynamic or should I go about this in a totally different way?
