Need two separate class lists for two product groups

Need two separate class lists for two product groups

Just getting started with Zoho Showtime.  We have two very different products we sell.  NONE of our classes would apply to both product categories.  Similarly, none of our clients would cross between product/class interest.

We will eventually start doing classes for both areas.  I don't see a way to make separate lists of classes (GoToTraining calls them Catalogs).  I need one list of classes related to product A.  Then I need another list of classes for product B.  Is this possible?

It's important because the two products are actually competing products we resell. In some cases, based on the lead source, we legally can't show the other competing product info at all.
