You can create groups of lists to organize and find necessary information faster.
Go to My Lists section and click on Choose a group to show,
Click on Add a new group,
Name the group and choose a list that you want to add to a group and click on Add to a group under Actions,
Choose a group from the drop-down.
Now you'll be able to filter out or exclude chosen groups. This also enables you to give custom access to chosen groups for sub-users. You can read more about custom sub-user access in What Are The Different Types Of Permissions? What Do They Stand For?
