There is a "JobVacancyContainer" component we use on a website, This component includes "JobVacancy" child componentes, which are the actual job descriptions.
Editing the component in CMS cockpit works as expected;

But, there is no option to edit the actual job description component.

How can I add this, so we can edit that as well?
The editor areas are as follows:
JobVacanciesSectionComponent:
<group qualifier="editorial" visible="true" initially-opened="false">
<label key="config.general.editorial" />
<property qualifier="JobVacanciesSectionComponent.headline"/>
<property qualifier="JobVacanciesSectionComponent.vacancyGroups"/>
<property qualifier="JobVacanciesSectionComponent.anchor"/>
</group>
JobVacancyContainerComponent:
<group qualifier="editorial" visible="true" initially-opened="false">
<label key="config.general.editorial" />
<property qualifier="JobVacancyContainerComponent.headline"/>
<property qualifier="JobVacancyContainerComponent.vacancies"/>
</group>
JobVacancyComponent (this is where I need to get somehow...?)
<group qualifier="editorial" visible="true" initially-opened="false">
<label key="config.general.editorial" />
<property qualifier="ParagraphComponent.headLine"/>
<property qualifier="ParagraphComponent.anchor"/>
<property qualifier="CMSParagraphComponent.content" editor="wysiwyg"/>
</group>
