How to use parameter with filter

[GammaGames]

I'm using the library with the template only method:

{% assets filters="jsmin", output="gen/packed.js",
          "common/jquery.js", "site/base.js", "site/widgets.js" %}
    <script type="text/javascript" src="{{ ASSET_URL }}"></script>
{% endassets %}

But I'm having an issue with the jsmin library stripping whitespace in my template strings, so that this is a test is turned into thisisatest. The jsmin library has the quote_chars=quote_chars="'\"`" parameter that should fix this, is there a way to pass the parameter to the template?
