Sync log: Change Display value of system object

Hi,

is there a way to edit the display value of the system object in the synchronization log?

I have a csv connection to import assignments into PersonHasESet.
These assignments are displayed as "UID_ESet - UID_Person" and I would like to change it to have "Ident_ESet - InternalName"


Do I need to customize the report (DPR_Journal_Summary) or change the display pattern in the table definition (I already tried %UID_ESet% - %UID_Person% but that had only impact on the display in the object browser)?

We are using One Identity Manager 9.1.1.

Best regards
Wolfgang
