Quick Query filter definition in Process Configuration Source

Hi everyone,

is it possible to define Plan View quick query filters in the Process Configuration XML of Project Areas or Process Templates?

So far I was able to find out that there is a filter definition for quick queries which can be added by the following declaration:

<filter definition="com.ibm.team.apt.filter.quickQuery"/>

What this does is it creates an empty quick query exclude filter in my Plan view.
The question is how can I fill it now?

If this is not possible maybe an enhancement like the following could be used?:

<filter definition="com.ibm.team.apt.filter.quickQuery">
   <parameters>
      <parameter key="!attribute1" value="value1"/>
      <parameter key="attribute2>" value="value2"/>
   </parameters>
</filter>

All given parameter elements would constitute a logical conjunction

Thanks!
