Topics in profile / noob question

Hello everyone, I'm new here. I've been flying drones for 12 years in various parts of the world. I learned about Pond5 from a colleague in the film industry who recommended it as a place to showcase my footage and promote sales to my clients. I have a question: Is it possible to create topics in my profile? I'd like to add a category like "Australia" and then create subtopics for different locations, so I can organize my footage. For instance, I have about 140TB of footage from Poland alone in ProRes422 4k. I'd like to categorize them by cities, landmarks, or activities. Any advice would be appreciated. Regards, Pawel (my IG: @pawelsudol_droner)
