At the moment, we have not implemented a feature for managing metadata objects and categories directly. However, we are actively working on developing a management console specifically designed for this purpose.

In the future you will be able to edit, remove and manage these objects by yourself. In the meantime, the Cital support team will be more than happy to assist you with any requests in this regard.
