The set of default MetaAvatars should be easily expandable

I've been working with the Meta SDK a bunch and for a local project I'd need a user to be able to select a custom avatar from a list from pre-made ones.

This as it turns out is not possible though since there currently is no way to export or extract a meta avatar from the VR headset. This was further confirmed here:

I'm not the only person who's run into the issue and the only solution I can think of is creating X meta accounts giving them a unique avatar each, which seems ridiculous.

I don't expect this message to change much, but I was told to do so by the people from the Meta Horizon Support team, so I rather give it a shot and also warn others about this issue.
