Defaulting new posts and media uploads to use “Registered” group

Hi,

I’m setting up a “private” self-hosted WordPress site to share my photos and videos with family and friends. I’ve managed to purchase and install the Widget Control Pro and Groups plugins, and have been able to apply the use of groups to successfully to restrict my posts and media attachment page content from the Internet at large. I’m aware the direct media URLs are unprotected at with this scheme, but they can’t really be guessed externally, and it does allow me easily share a specific image/video with un-registered individuals.

So in a nutshell, “all good.” However, this scheme implies that I need to remember to always manually assign at least one group ID to every post and media file, lest it remain unprotected. To avoid the potential for mishap — is there any way to configure the system to automatically apply the built-in “Registered” group ID for every new post and media upload?
