Question: Recommended way to modify replacements?

[stormwatch]

Hi. I am aware I can edit my /etc/fonts/conf.d/37-repl-global-free.conf and comment the parts I don't want out but maybe there is a better way?

My local fontconfig configuration in ~/.config/fontconfig/fonts.conf is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<fontconfig>
  <match>
    <test name="family">
      <string>sans-serif</string>
    </test>
    <edit binding="strong" mode="prepend" name="family">
      <string>Calibri</string>
    </edit>
  </match>
  <match>
    <test name="family">
      <string>serif</string>
    </test>
    <edit binding="strong" mode="prepend" name="family">
      <string>Cambria</string>
    </edit>
  </match>
  <match>
    <test name="family">
      <string>monospace</string>
    </test>
    <edit binding="strong" mode="prepend" name="family">
      <string>Consolas</string>
    </edit>
  </match>
</fontconfig>
