Feature Request: Upload JSON file for attributes on Claim Page

Hi, while trying to create a claim page with multiple attributes, it gets very time consuming to do it manually on claim page, is there a possibility to upload JSON files to set attributes on claim page app?

The claim page is setup to claim just one token - Are you looking to do different tokens with unique artwork?

Nope, just the one artwork, but a LOT of attributes so would be easier to be able to upload JSON file for attributes, description etc
