By default, the hero vs villain report displays winnings in chips. I'm hoping to create a similar report that displays net won/lost vs villain(s) expressed in BB.

From searching, it appears that it is not possible to edit that report directly.

Is it possible to create a new report from scratch that has my intended functionality? MTTs, if it matters. Thanks.

Unfortunately that's not possible. The 'Hero vs Villain' report requires special work behind the scenes to filter the data and as a result the report cannot be edited or recreated elsewhere.

Is it possible to obtain this information in any other fashion (outside of a report)? Even if on a player by player basis, via some sort of filter or custom statistic?

Unfortunately I don't know of a method to obtain that data outside of the 'Hero vs Villain' report.
