Online CUs must contact a Client Service Representative to make these changes to your configuration. (You can, however, view the configuration using Tool #961 "Audit Reg E Triggers for Stmts." As long as you let us know before the last day of a month we can make the changes to your configuration before statements are generated on the 1st.
(Self Processors can change these settings via OPER > MNOP09 "Member Statement Config.")
