The program only populates the ladders as they progress, so there isn't a current mechanism for having them completely filled out as the tournament starts.  There are links under each name in the ladder (e.g. A-1, B-4) that describe where the wrestler in a given position comes from (A means top half of previous match, B means bottom half, number is the bout number).  It is therefore possible for someone to determine who they will compete against and in which round.

I have submitted an enhancement request for prepopulating round-robin brackets per your request.  It should appear in a future version of the program.
