Configuring HTML template for footnotes

I’m using blackfriday’s support for footnotes:

Hello. [^1]

[^1]: This is a footnote.

This renders roughly as:

  <sup><a href="#fn:1">1</a>

<div class="footnotes">
    <li id="fn:1">This is a footnote.</li>

All good.

However I would like to customize this template. For example, instead of <hr/> I would love to just add a small <p class="strong">Footnotes</p> title.

I’d look at and see if there’s an option there. Doesn’t look like it.
