Is it possible to add custom fields to the UI of inline elements?

Hi everyone,

I have a question about customizing the document field. I'd like to add an "Open in new tab" checkbox to the link editing interface. I need this property to be saved along with the URL (for example, as a target="_blank" attribute) and be available for front-end rendering.

I know that componentBlocks allows for creating custom block elements. But is there a way to do the same for built-in inline elements, such as links?
