If i understood you correctly the use case is
Given a user has already granted consent
and the cookie is set
When a new tag tech is deployed
and does not belong to an existing category
Then the user should be shown the consent manager to allow them to opt-in to the new category and review their consent preferences.
In order to acheive this you can use a custom js extension to check if the consent for the new category has been given. If it has not been granted you can use the following method to call the consent manager.
You will also need to alter the behaviour of the consent manager save button to drop an additional cookie or local storage to flag that the user has responsded, so that it does not show up each time if the user opted out.
i would also run this for a short period of time only, depending on your traffic stats.
Hope that helps
