All chat can be suppressed or redirected to one of the chat windows via your user control panel. Also, Alinco3 allows you to direct chat output to specific windows (it allows you to change text colors, too).
Is that what you were asking? If you want to output chat to another Windows window, from multiple clients, I don't think you can. If it possible, all of the multi-account UCM's would never have to worry about missing +Envoy tells to an inactive window.
