Long story short, my company is storing some unsupported file types in PDM with some manual management of revisions going on via the API. Obviously PDM is not getting thumnails from these files and is not displaying anything in the Preview section in Explorer.

I assumed there would be some sort of way to manually provide an image to a PDM file object, but I can't find anything in the API docs for manually setting a preview. Only retrieving one.

There there some API endpoint I can use to provide a properly formatted image manually to populate the image preview in Explorer for unsupported file types?
