If the editor would like to make a link that's a different size than the body text links (using H1-H6's styling), currently that is not possible because when designing the styling of links... it's tied to all links within the rich text, not per text style.
Hi there! Thank you so much for submitting this Wishlist request!
A current workaround which many customers are using is our custom code embed within Rich Text Elements.
What you can do is create styles associated with a specific class for links, then use the following code snippet for custom styled links.
<a href="google.com" class="link-class-name">Text</a>
