Subcategories?

I’m trying to set up the following using this plugin:

1. A home page with five parent categories, shown as a masonry portfolio view, let’s call them A-E
2. Each A-E parent category links to a second portfolio view with the subcategories for each parent category A-E (A shows subcategory portfolio items aa, ab, ac, etc.)
3. The second portfolio view links to a third portfolio view that actually shows the gallery images (aa, ab, ac, etc. link to a portfolio of images for aa, ab, ac, etc.)

Hopefully this is clear enough. I’m not sure this plugin supports this type of nested portfolios but if it does, or another plugin is more purpose-built for this, I appreciate all help!
