Analysis Workspace: Projects available through search

In my organization, workspace projects are shared a lot.  it would be great if we could have the option to somehow make projects visible through search only so they do not clutter the project list.  for example, we have created a ton of "starter dashboards" for educational purposes.  this clutters the list.  it would be great if they would only show up if a user searches for them, or chooses to 'pin' it.  It may also be nice to be able to organize workspaces.
