Require user to be logged in to download

I’m not sure if the plugin supports this or not but is there a way to require the user to be logged in to download their downloads? Currently, after a user purchases a download they receive a direct download link but I can be logged out and still use that download link. Basically I don’t want customers to share that link around the Internet.

If not, I think I may have an idea of how to accomplish this. I will probably have to associate a name with the download link and somehow I should match the current logged in customer name to the download name in order to enable a download. Is anything like this included in the plugin?

Thanks,
