Keeping Groups Not Visable

I'm creating two Group Categories. One category is for "Tickers Groups" and the other is the "User's Groups". What I'd like to see if it's all possible, is to hide the Ticket Group category (Which I have already done) and allow the User's Group to remain visible. I see I Can still access the groups within the Ticker's Groups category, which is exactly what I want.

Now, what I'd like to do is to be able to hide the groups within the Ticker Groups category so they do not show up in the list when the member clicks on Groups from the navigation bar because we will be creating a script that auto create in excess of 20K groups (1 for each stock ticker) within the Tickers Group category. However, the user will be able to find the Ticker Group using the search feature.

The only groups I want listed are those that are in the User's Groups category. Is something that is possible?

Thank you
