DXP ToolKit strictly offers personalization features, that is to say dynamic content based on a given user persona. Categories and tags are not attributes of a user persona, and thus are rules for dynamic content, but not for personalization. Because of that, DXP ToolKit does not currently offer persona rules based on the attributes of a post or page.
If you feel you need this feature, consider adding custom persona rules to DXP ToolKit or reach out to us for help!
