Organize Custom Mini

What Feature would you like to see included within TaleSpire?
Organizing Custom Minis

Preferably into a folder system like how Talespire already has sorted Minis into the Aberration, Beast, Celestial, etc. under the MEDIEVAL FANTASY group.

What situations would this Feature be useful?

I tried to create sub folders to the Local Content Pack but files in sub folders do not show up in Talespire when I open the program.
My group has a fair number of 3d artists and tech artists so we have currently added 99 custom models and are looking to add around 100 more.
So I would really appreciate some way to organize them into folders like the Models that come with Talespire.
