Additional Users for EX8000 X6 Range Extender

Actually, this request is for the EX8000 X6 Range Extender.  (Please update your drop down of choices for devices).  I have a USB external drive attached to the USB port of the EX8000.  I have a client device (a camera) which requires ftp to have UserID/Password.  However the EX8000 ftp server can only configured with either "Password Off" (Default) or "Password On".  If I select "Password On", I have to use the Admin password for my client to connect to the EX8000 ftp server, which I DON'T LIKE.

Please allow the EX8000 to set up additional users so I can create a user just for ftp.

Thank you in advance.
