Allow selecting link destinations in an existing table of contents

[75th]

I want to make a docset from some HTML that I've scraped (naturally). All the main doc pages, no matter what Dash data type they represented, are top-level members of the same folder. So I can't distinguish data types by path.

Fortunately, these docs have a very well-formatted table of contents already. What I'd like to do is just point Dashing at those links, and have it use their href attribute as the doc page, instead of just marking that element of the ToC itself. But it doesn't seem like Dashing allows that.

(If this is already possible, please let me know. Otherwise, I'm going to poke around and see if there's any hope at me being able to contribute this change.)

I found the ability to do the "selector": { "attr": "href" } thing and thought it was the answer to my problem. But it doesn't seem to do anything by itself, and I think it's only to get the plain text name of the entity, not its path. So I'm back to not knowing what to do.
