Mac Mail Message Links?

Hi folks, first time post, so not sure if its in the right place. As an Omnifocus user for many years I have gotten into the habit of using Mac Mails URL scheme for linking back to emails from to-do lists etc. I created a personal work board using a basic GTD methodology. I presumed I would be able to use/create a link column to populate link backs to email messages for reference. However, it added a https:// before the local link and I see no way to disable it. I believe it would be a very useful feature. The URL scheme is already in place. A small change could accommodate message URLS also?
For reference, the URL scheme for linking locally to an email begins: “message://%3C9rxVA5ZATq…etc”
Thanks for any advice.
