I am wondering if it is possible to add a dependency to an asset store product in a project's Packages/manifest.json. The end goal would be this: Have an asset on the asset store. Make a public "Samples" project repository for that asset on github. Make that "Samples" project's manifest.json include a dependency to the store asset. When a user downloads & opens the "Samples" project, if they have purchased the original asset, it is automatically imported into the project. If they haven't purchased the original asset, it is not imported and errors show up. Is this currently possible?
