Pass custom fields from CB to Joomla user

Currently, when a CB user is created, the user is also created in Joomla! users. Is there a way to map CB custom fields to Joomla! user fields?

Reason this is needed: We are implementing ActiveCampaign. ActiveCampaign does not interface with CB. When a new user registers, ActiveCampaign pulls the user information from Joomla! users. We need information from the CB custom fields to pass over to ActiveCampaign so we can filter based on those fields.

Thanks!

You could push that data to Joomlas database table using CB Auto Actions and a Query action. Beyond that nope as CB is intended to be used as a replacement for Joomla profiles.
