Show category titles within list of products

[abcschooldr]

Is there a way to include category headings (section headings) within a category? My store lists all products in a cumulative category (ALL Nevada Real Estate Courses) and I also link all these products to section categories. My cumulative category is there for users that like to scroll and the products are broken down into smaller categories for users that like to click. Is there a way to show the smaller category headings within the cumulative category so there is more organization? Right now they are all equal categories with products linked from the cumulative category.
