Can you create a folder on an admin level?

We use Smartsheet for many different projects. Since 2018 we have accumulated many sheets. These sheets are shared with many users, in different departments. Is there a way to organize these sheets on an admin level, for example by construction year, without having to set up the same folders on a user level, over and over again?

Going forward we are going to use Workspaces. I'm trying to navigate past years.
