Reporting spam with Spmassassin-run instead of sa-learn

At the moment I run sa-learn for learning new messages as spam/ham. The problem with this is that it just reports to bayes, not razor2, pyzor, dcc or spamcop.

It is stated in the spamassassin-run manual that spamassassin-run is for reporting to these places, and to use sa-learn only if I want to report to bayes locally.

My problem is that I use a DB for user preferences and different bays DBs for every user. This works with sa-learn by specifying "-u <username>", but I can't seem to find this option in the spamassassin command. It defaults as "root" for me.

So basicly, I want to run the "spamassassin --revoke/--report" commands as a specific username. How can I do that?
