Multiple RPMSG channels between PRU and Linux?

Hello, I am using the PRU to create multiple transceivers and I am trying to use the rpmsg_pru functions to create multiple /dev/rpmsg_pru** entries for each individual transceiver. Currently in all examples I see, PRU0 is restricted to use Port 30 and PRU1 is restricted to use Port 31. Is it possible to use any other port for these devices or create multiple channels from the same pru? Even when changing the port number in my pru_rpmsg_channel declaration to something other than 30, the device entry still shows up as 30.
