wireless client names empty

Hello,
I think I might be just be searching for the wrong things, but I’m wondering if it’s possible to list the wireless client’s names in the results from:

/interface wireless registration-table print

currently mine looks like:

 # INTERFACE	RADIO-NAME       MAC-ADDRESS       AP  SIGNAL-STRENGTH TX-RATE UPTIME               
 0 wlan1		xx:xx:xx:xx:xx:xx	no  -56dBm@1Mbps    65Mb... 21m10s               
 1 wlan1		xx:xx:xx:xx:xx:xx	no  -56dBm@1Mbps    72.2... 21m10s               
 2 wlan1		xx:xx:xx:xx:xx:xx	no  -48dBm@1Mbps    72.2... 21m10s               
 3 wlan1		xx:xx:xx:xx:xx:xx 	no  -58dBm@6Mbps    11Mbps  21m8s

I’m guessing that “radio-name” should be filled in, but it appears to be empty.

When I say wireless client names, I mean I’d like to see “jens iphone” or “company laptop” (what is the correct term for that?)
