About renaming _paq

Hi,

I am using several tracking products such as GA and Piwik at the same time. My problem is that Piwik force its option varialbe (_paq). Is there a way to configure (dynamically) the option variable Piwik is used?

something like:

<script>
var PIWIK_OPTION_VARIABLE = "_paq";
var _paq = _paq || [];
</script>

or

<script>
var _paq = _paq || [];
var PIWIK_OPTION_VARIABLE = _paq;
</script>
