┬┐have you tried invoking it with -T?

"asks (-T)
Display a list of the major tasks and their comments. Comments are efined using the esccommand."

From what i understand it's the closes you can get to what you are iming for, but just by reading the documentation it seems there is no quivalent option, maybe you should just include the "verbose true" and nowrite true" on you file as you metion.

(the -T will only display the tasks that have a defined comment).
