Access theme assets folder in settings_data.json

[Luukas]

Hi,

To access library (Content->Files) files in settings_data.json we can use prefix "shopify://shop_images/...". Is there a prefix/url to access current/active theme assets folder?

I've also seen urls like "shopify://collection/.." and so on, but wasn't able to guess the correct one for assets folder. Is this doable? I keep getting "Setting 'logo' must be a valid shopify url" error.

Is there a definitive list of valid shopify urls? 

Thanks.
