Set up Report Catalog
In the report catalog, you can restrict access to folders from certain user groups as well as create custom folders and assign reports to those folder.

Add Catalog
You can use the Add Catalog option to create a new folder. In this example, we created a Dispatchers Reports folder.

You can use the Arrows to rearrange the folders to the order you would like them to be displayed in the reporting sections.
Add Reports
Use the Add Reports to get a list to look up reports to add to that folder.

Security groups
You can use the security groups to secure any folder to allow only certain user groups can see that folder's reports.

This section would allow you to give permissions to only certain users. You could set all System groups to be TMS Admins only and then create folders that only certain groups can have access to.
