you are able to put icons in other columns as the first in MDX, according to its help file.
[indent#] [+flags] [icon#] [overlay#] [state#] [text]{tab}[+flags] [icon#] [overlay#] [state#] [text]{tab}...
try: did -a dialogname id 0 + 0 0 0 Column1 $chr(9) + 1 0 0 Text here with an icon.
I havent tried this in MDX though i reckon it should work, i know for a fact this is possible in
DCX .
