I use Joplin (a markdown editor) a lot. In particular, I use it for storing Hook links.
Joplin per se supports deep linking; however, at this stage, these links are not usable outside of Joplin.
Perhaps you could get in touch with the developer. The Joplin forum is at Joplin Forum - Joplin Forum. He also has a Github page (cannot post the link due to the discourse limitations).
