Is there a *_url helper for jekyll_archives?

So I’m using jekyll-archives and it does what it should. But how do I create a link to a category or tag archive? I have this in config

  enabled: [ categories ]
    category: '/c/:name/'

and this in my layout

<a href="/c/{{ page.category | slugify }}">{{ page.category }}</a>`

which doesn’t feel very DRY… I assume I’d appreciate something along the lines of {% archive_url category: page.category %} is there anything available? Or, should I add it? Regards
