What are the "additional flags" referred to in the SAP BusinessObjects Server Manager?

Using the "Set Logging Flag" allows us to track the users who have accessed a BPC environment in a given time period. Unforntunately, each of the flags (ALL, SEND & RETRIEVE) when enabled, insert a large number of records into the log Table (tblLogs). If possible we would like to only track JobName = CheckAccessSecurity.

Is it possible to restrict the logging in this manner using the Set logging Flag - Additional Flags?
