How do you share Projects with all Signed-In Users. - by default?

I'm simply looking for a way to share all new projects - by default - with all users that are signed-in. The users in this particular site need the ability to see everyone's projects when they are saved/created. Is there a way to share all projects when the project is created by default without having to use the sharing tools? Out of the box, the project is not shared with anyone and is only available to the creator and I do not see the config to change this. I would prefer not to have to rely on users remembering to share their project and just share it by default when it's created... is this possible?
