Content Categorizer- Security Group value

Hi All,

We are using TITUS Document Classification tool.

We need to integrate it with WebCenter Content to map the Classification mentioned in the document with the SecurityGroup defined in the WebCenter Content.

We have same values for Document Classification in TITUS and Security Groups in WebCenter Content.

We are using ADF WebUI, so content categorize button is not available in the upload form like in Native UI.

Is it possible to call the content categorizer service from Pre-Check In filter?

Or please suggest me the best practices to use Content categorizer to extract value from document and use it as metadata value.
