Extend SharePoint Audit Logs

Hello,

In my application i process audit logs to get the items that have been changed. Once audit entry is got, then i run SPSiteDataQuery to be able to get ListId of particular item, as SPAuditEntry does not expose that property.

This works ok, however for big number of audit entries it works very slow,e.g. 10K audit logs take around 12 mins to run all this data queries.

I am wondering is there a way to extend out of box audit log writing, so right in the process of logging it writes also ListId in the log?

Thanks,

Hrayr
