A simple USB question

Hi! I have an AT91SAM7S-EK kit with an AT91SAM7S256 microcontroller.
This microcontroller supports 4 Endpoints - EP0, EP1, EP2 and EP3. I
am using the USB to communicate with a legacy application running on
the PC. This application can only communicate on a COM port. So, I use
the USB to provide a virtual COM port on the PC with which this
application can communicate. My question is - Can I create more than 1
virtual COM port on the PC with 1 USB connection?
