Is there an ootb way to make RTE / Multieditor required on a Content Fragment in AEM 6.5?

Is there an out-of-the-box option to make `sling:resourceType="dam/cfm/admin/components/authoring/contenteditor/multieditor"` as "required", that we are using on a content fragment in AEM 6.5? 

<_x0031_589920765450
        jcr:primaryType="nt:unstructured"
        sling:resourceType="dam/cfm/admin/components/authoring/contenteditor/multieditor"
        cfm-element="Header"
        default-mime-type="text/html"
        listOrder="3"
        metaType="text-multi"
        name="title"
        renderReadOnly="false"
        showEmptyInReadOnly="true"
        valueType="string"/>

We are not able to use "required=true" 

Found a custom solution http://experience-aem.blogspot.com/2018/10/aem-6420-assets-content-fragments-coral-3-composite-multifield.html but do not want to implement.
