This is my first TP-Link router. How do I add more than one samba share? Lets say for example, I have 3 folders on a USB drive. I want to use one share to access two of the folders with it's own username and password and the third folder I want another samba share to access this folder with a different user name and password. I see no way to do this. All I see is a admin user and a visit user to access one share only that can be any of the folders on the USB drive. Well this just won't do. Linksys routers make it so simple. Am I missing anything here? 

This is a new router that I'm sure nobody has yet, but the interface is similar to the latest Wifi 7 Archer routers.
