Something along the lines of:

<dtml-in name="Catalog">
    <dtml-with name="getObject">
        <dtml-var name="ZClassMethod">
    </dtml-with>
</dtml-in>

or

<dtml-in name="Catalog">
    <dtml-var expr="getObject().ZClassMethod(_.None,_)">
</dtml-in>

Will call a method of an object returned as a ZCatalog result.
Substitute the name of your method for "ZClassMethod".
