Campaign editor overrides href value

Campaign editor overrides href value

I've been trying to insert a deep link in an email campaign so recipients can directly open a native app on their device. My deep link looks something like "myapp://".
The options to insert links in the campaign editor are limited to strict urls, emails, anchors or phone. If I try to embed the deep link as a url, the editor automatically rewrites prepending "http://" to it, which I do not want.

I've tried to embed my deep link writing custom html, but as soon as I save it, the editor automatically replaces my anchor href value to rel="noopener noreferrer".
Is there any way to prevent the editor from overriding and rewriting my code or another option to insert a deep link like the one I'm mentioning? 

Thank you!
