[RTTY] fldigi question

[Lee]

Is there a way to make callsigns highlight in different colors (i.e. red for 
dupe, blue or green for unworked) like N1MM? If I double click on a callsign 
it'll show up in red in the callsign field if it's a dupe but I'd rather see 
the colors in the callsigns as they appear in the receive window. I've been 
trying to find an answer in the fldigi manual but nothing so far.
