How to write TWO output endpoints in ONE usb device using NUMEGA Driverwork?

I develop usb device driver using Numega DriverWork
there are 2 output endpoint in my device
AP call CreateFile() and WriteFile() to write data to driver
and KDevice.Write() write data to ONE endpoint

how AP write data to another endpoint by calling WriteFile()
there are only one KDevice.Write() while can write data to the pipe.

Do I need another KDevice ?
