If you have good knowledge on JS then you can customize this "link-options.js", I have done similar implementation in classic UI, but not in Touch UI. you need to put some additional effort for R&D
Another approach is you can write a sling model, that reads the content of the rich text editor, and inside the sling model use regex to find out anchor links and replace anchor links by adding custom attributes.
My preferable approach is, you are adding custom attributes for analytics tracking, I feel, on click on the anchor link you can call below function, link name you can read from the anchor link title. Link type and id either you can hardcode or you can write some logic.
function trackLink(link) {
if (typeof _satellite !== "undefined" && typeof digitalData !== "undefined" ) {
digitalData.page.link.name = "Privacy Policy";
digitalData.page.link.type = "LINK";
digitalData.page.link.id = "your custom id specific logic";
_satellite.track('anchorLink');
}
}
