Forum different sidebar blocks usergroups
 

We have on our forum 2 style templates..

1 = default and the other one = commercial free.

Our forum is about trucks and their drivers... Therefor we use the sidebar for news information and traffic announcements also some commercial ads will be shown there.

Now thats our problem. We want the ads to be shown in the default template only and the news and traffic announcements should be shown on both templates.
Is there a possibilty to do that in de blocks manager or another way ?

i hope you understand what i mean.
