Is it possible to pass a per-appmod-opaque to appmods under a common servername/port?

ErlyWeb is expecting <opaque>appname=blog</opaque> for each app.

docroot = /path/to/app/www
appmods = <[UrlPrefix], erlyweb>
<opaque>
appname = [AppName]
</opaque>

but for more than one appmod in a server,

docroot = /path/to/app/www
appmods = <[UrlPrefix], erlyweb> <[UrlPrefix_2], erlyweb>
<opaque>
appname = [AppName]
</opaque>
how would I pass a unique opaque to each appmod?

Thanks,

Robin
