Hello,
You can import custom fields the same as regular fields as long as your list of available fields is up-to-date. In
this article we explain how to do it for Joomla articles but the same applies for all Joomla core extensions.
The name of the fields can be the same as the fields known by RO CSVI then you do not need to map them in your template, otherwise you can simply map them out in the template and RO CSVI will import them like that.
Kind regards,
RolandD
