Customizing status message on per service basis?

[Rob Stampfli]

This may well be in the FAQ, but I can't find it anywhere:

When you set your status in Pidgin (Available, Unavailable, Away, etc.)
you are allowed to enter a short message that others see attributed to
you in their buddy list window.  Is there some way to set these messages
selectively on a service by service basis?  In other words, set one
message for MSN, another for Yahoo, a third for ICQ, etc.?

Thanks in advance,
Rob
