That's not a supported feature; the data in the address columns is
generated from pinfo->{dl_src,net_src,src} and pinfo->{dl_dst,net_dst,
dst}.

No, but you can get the address as a binary value from pinfo-
>{src,dst} and then convert it to a string using ip_to_str() or
ip_to_str_buf() for IPv4 addresses and ip6_to_str() or
ip6_to_str_buf() for IPv6 addresses (or address_to_str() or
address_to_str_buf() if you have an address structure and want to
handle all possible address types). The expectation is that the
address-as-a-string would be used only for stuff to be shown directly
to users, and that a dissector would do all the other work with binary
addresses.
