Is it possible to have 2 CDC ACM serial ports?

I've got the USB CDC ACM example up and running. I'd like to do something similar on the nrf52840 Dongle but rather than using a UART for the CLI, I'd like to use a second virtual comm port.

My end goal is to use one VCP for data comms, and the second VCP for debug/logging.

Is this possible with the existing software? Are there any examples around that show what's needed?
