Parameterized location of displaytag.properties

Could it be possible to let the location (and maybe the name too) of displaytag.properties be specified in the web.xml as a context-param like in the following example and use the default location (classpath:/displaytag.properties) by default ?

<context-param>
    <param-name>displayTagConfigLocation</param-name>
    <param-value>META-INF/tags/displaytag.properties</param-value>
</context-param>

it would allow people to manage their properties files the way they prefer (like specifying jstl application resources with the context-param javax.servlet.jsp.jstl.fmt.localizationContext).

thanks,
