Textarea link button popup enhancement?

Hi, is it possible to have the extended version of the textarea link popup when adding it - to also have text fields for filling in ‘rel’ and ‘class’ properties, and maybe a toggle for the ‘target _blank’? It might bring in additional user friendliness - because not every panel user from my company’s clients is going to successfully google how to manually make a textarea link in the panel open in a new tab.

The markdown field has this feature, among many other improvements to the core textarea.
