Hey @djones if you're still looking into this, our Office Hours could be a good format for getting ideas for how to build a way to update Retool Storage metadata (like the make public flag) in a group including Retool Community Support Engineers and other experts from the community 
If you do join an Office Hours session, you could then share learnings back here as a Solution 
. I'm sure that'd be useful for others searching for how to build similar functionality!
