The only way to do so involves writing code. You'd have to add a new
column type (there is a fixed set of things you can put into columns)
*AND* you'd have to modify the dissectors that generate those times to
fill in columns of that type.

It's not as easy as call-to-response times, given that, for
call-to-response times, you take the time between a call and a matching
response, but there's no notion of "matching" here, just a notion of
"from the same client to the same server" - which could be tricky if the
requests and responses are going over a connectionless protocol such as
UDP and requests go to one of the server's addresses but replies come
back from another of those addresses. That could be done using the
conversation set up for ONC RPC over UDP. For connection-oriented
protocols, you might have to worry about multiple connections, though,
if the client opens multiple connections to the server.
