replication agents customisation

Hi,

How can I pass some parameters (or filters) to replicators replication method (replicate(Session session, ReplicationActionType type, String path,
                  ReplicationOptions options)) so that it should replicate content like

from author content path will  be /content/dam/folder1/folder2/parentfolder/abc.jpg to another author (or publish), but the path needs to be truncated. It should be  /content/dam/parentfolder/abc.jpg (there are no folder1/folder2).
