Showing resolved and unresolved column at the same time

Hi

I have a problem with the name resolution in wireshark 1.6.2 on ubuntu. I want to display both the IP and , when possible, the resolved ip in two separate columns. I added both the Src addr (resolved) and Src adr (unresolved). The problem is that both column always show the same value. Either the resolved value or the IP depending on name resolution settings.I have the same behaviour in tshark.

my column format column.format: "No.", "%m",
"Time", "%t",
"Src unres", "%us",
"Source", "%rs",
"Source port", "%uS",
"Destination", "%rd",
"Destination", "%ud",
"Dst port", "%uD",
"Protocol", "%p",
"Length", "%L",
"Info", "%i"
