Skeltal Skinning help

I’m new to Blender and the Skeltal Skinning system, and I’m trying make a human type avatar, I followed this guide on GitHub but I wish to know, when you import the custom “creation” or avatar, how do you set it as your default avatar type? Any help is useful! Thanks!

Since this feature is not released yet, finding proper support on here may be difficult.

However, I believe in this link:

Under the subsection " New Character Controller", there is a download link to a ROBLOX place file. I think ROBLOX used the new skinning system for a character and set it to default. Read through the scripts in the game to see how they did it.
