When you click the flag button on a message in the chat window, it reads "flag for moderator", and a dialog with an explanation field pops up.
When you click the flag button on a message in the transcript or on the star wall, it reads "flag as spam/offensive" and the flag is immediately raised.
Is it possible to raise a "moderator" style flag (with the explanation) from the transcript if it is no longer in the current chat window?
It seems it can somewhat be done by repeatedly clicking "load older messages" in the chat window until the message in question is in view and flagging from there; is there an easier way?
