🎯 Goal / Objective

A clear and concise description of what this task aims to achieve. Why is this task important?

Bone data in the app is organized by "boneset," sets of related bones based on individual PowerPoint files where we're getting our data. But they are currently all pooled into the same parent folder, making the data hard to browse through and modify in case adjustments are needed.
