Manually grab .json files that Studio uses for the Available tab in Smart Content?
Background: I use DIM to handle all of my content installation needs. I run Studio in offline mode. That said, I like to use Smart Content as my product browser in Studio. DIM-installed content appears in the Smart Content pane mostly without issue, and any missing products are easily added through Content DB Maintenance>Re-Import metadata for the troublesome product. Again, all offline.
I would also like to use the Smart Content "Available" tab as a browser for my purchaed and not-yet-installed content. So far, though, I don't know how to keep that tab updated with new purchases. I got the initial set of purchased products to appear by letting Studio go online and update metadata. After the update, I fixed all the individual missing icon errors by adding or resizing the product images in the data/cloud/meta folder. I am afraid that If I let Studio update the metadata again to capture all my new purchases, it will overwrite my custom metadata. So I need a way to update Available content without overwriting my curated metadata.
Getting images for the products' 1_<product ID>.jpg is not an issue.
Is there a way to get/download the matching .json files that are also in the data/cloud/meta folder? It seems that the pair of files, .jpg and .json are all that's needed for Smart Content to grab the product info and display its icon in the Available tab.
Thanks in advance for any help or insight.

Unfortunately, functional Available tab requires Daz Connect Login and Update Metadata. Update Metadata does update cms database as well as thumbnail images. For thumbnail images, you can try setting Read-Only on them but for updating cms, you have no way to prevent it ~~
Thank you. I was afraid of that. I still have the Installed tab to look at and browse, so like I always told my kids: "Some is better than none."
