Cloudfront CDN minified CSS cache busting

    How can I force W3TC to use a different filename when creating minified files?

    For instance let’s say the following CSS files are being minified (manually selected on the Minify settings at http://mysite/wp-admin/admin.php?page=w3tc_minify) 

    http://mysite/wp-content/theme/mytheme/style1.css
http://mysite/wp-content/theme/mytheme/style2.css

    If I update these files and re-minify the name of the minified CSS file remains the same, even though the content of the file has changed. I need the name of the minified CSS file to change so the CDN will see and immediately serve this new file on page refresh.

    If I add a cache buster to the filename a new minified file name is generated:

    http://mysite/wp-content/theme/mytheme/style1.css?2

    However I get the following error when attempting to minify:

    Recently an error occurred while creating the CSS / JS minify cache: File "/var/www/wp-content/themes/mytheme/style1.css?2" doesn't exist.

    And the minified CSS file no longer contains style1.css

    How can I either:

    A) Force a new minified CSS file name when the file contents change. (And not when filenames change)
    B) Use query variables when manually entering CSS files to minifiy.
