It's not CSV type, as you cannot add now columns to the list. It's more list a key to values dict, where the key is the category, and entity identifiers are the values. For example, a common use case for a custom list is to create a category called "VIP Assets". In the playbook, we can check if one of the involved entities (User, Host) is part of the VIP list, and go to a different branch based on the results.

thanks for answering. I see. I think It will still be useful on our case scenario but editing of values dict would be a challenge since it is raw dict/json string.
