Importing brushes and using brushes other than boring, simple vectors?

Toon Boom Harmony ESSENTIALS 14. I see that I have the option to import brushes in essentials… but I can’t have any bit map brushes with my version? I’m aware there are vector brushes that look like bitmap… anyway what kind of files do I use to import brushes into Essentials? Can I actually use “sketching/storyboarding” brushes or just any brush that isn’t boring? I’ve been stuck with using just the default brush tool, as I supposedly can’t have any textures in Essentials. Is there any way around this? Is there any way to spice up my line art in Essentials?
