You would need to create custom statistics to add that information to a hand report - see
this guide for the basics on custom statistics creation.
cash_hand_player_statistics.amt_x_bet_made (where
x is the street) is the size of the bet made by the player but if you want the size of the bet faced then you would need to use
cash_hand_player_statistics.amt_x_bet_facing instead (for a tournament statistic just substitute all instances of 'cash' with 'tourney'). To get the size in BBs you will also need to divide by cash_limit.amt_bb or tourney_blinds.amt_bb.
