<cache> settings in Hibernate mapping files generated by Middlegen

Is it possible to set the <cache usage="..."> tags in the hibernate
mapping files, when using middlegen to generate the mappings?

My build.xml reads as follows:

       <target name="middlegen" description="Run Middlegen to generate .hbm from live running database" >
                <echo message="Class path = ${basedir}"/>
                <taskdef
                        name="middlegen"
                        classname="middlegen.MiddlegenTask" />
                <property name="name" value="foo"/>
                <middlegen
                                appname="${name}"
                                prefsdir="${src}"
                                gui="${gui}"
                                databaseurl="${database.url}"
                                initialContextFactory="${java.naming.factory.initial}"
                                providerURL="${java.naming.provider.url}"
                                datasourceJNDIName="${datasource.jndi.name}"
                                driver="${database.driver}"
                                username="${database.userid}"
                                password="${database.password}"
                                schema="${database.schema}"
                                catalog="${database.catalog}" >
                        <hibernate
                                destination="${src}"
                                package="com.foo.db"
                                javaTypeMapper="middlegen.plugins.hibernate.HibernateJavaTypeMapper"
                                standardGeneratorScheme="vm"
                        />
                </middlegen>
        </target>

Mapping files that created look, for example, like this:

    <hibernate-mapping>
    <!--
	Created by the Middlegen Hibernate plugin 2.1

	http://boss.bekk.no/boss/middlegen/
	http://www.hibernate.org/
    -->

    <class
	name="Account"
	table="account"
    >
	<id
	    name="id"
	    type="java.lang.Integer"
	    column="id"
	>
	    <generator class="vm" />
	</id>
	...

I'd really like the mapping files to have, say, this:

    <class
	name="Account"
	table="account"
    >
	<cache usage="read-write"/>   <----- this is what I want to have added!
	<id
	    name="id"
	    type="java.lang.Integer"
	    column="id"
	>
	    <generator class="vm" />
	</id>
	...

How do I do this?

Thanks,
