Interest Categories

We're implementing Interest Categories for the first time (have been on LO for a number of years).


On the subscription management page, is there a way to hide sub/child interest groups? We want to use these internally and then use the top level/parent opt out group to suppress anyone that no longer wants to receive related messages.


However, with how we were thinking about using this, there would be an overwhelming number of sub interests publicly listed on this page.


Any workarounds? Suggestions about how your org uses this function that might be helpful?
