Will there be an NAS-5GS over UDP dissector?

We are using our own Softwaretool, to get Signalling from mobile phones and then send it to Wireshark via Network Loopback-adapapter as GSMTab or UDP packet for further analysis.

This works great for all Signaling information except NAS-5GS, because (unlike LTE NAS-EPS) there is no dissector nas_5g_udp.

So will there be an according dissector in a future release of wireshark, or is there another way, to send the NAS-5GS to Wireshirk over UDP for analysis?

There's a feature now to stream the PDU's over TCP, each preceded by a 16 bit length indication, for use with Decode As to define the port.

If you would someone to add UDP transport you could file an enhancement issue here.
