Transforms/props event filtering

Hello,
I would like to sent to nullQueue some windows security events based on some regex. So I have defined:

props.conf

[WinEventLog:Security]
TRANSFORMS-set= setnull,pruneprocesses,pruneusers,prunemachines,setparsing

transforms.conf

[setnull]
REGEX = .
DEST_KEY = queue
FORMAT = nullQueue

[pruneprocesses]
REGEX = Process\s+Name:\s*.*?(svchost.exe|lsass.exe) 
DEST_KEY= queue
FORMAT = nullQueue

[pruneusers]
REGEX = Account\s+Name:\s*.*?(-|SYSTEM) 
DEST_KEY= queue
FORMAT = nullQueue

[prunemachines]
REGEX = Account\s+Name:\s+[A-Z0-9-]+[\$]
DEST_KEY= queue
FORMAT = nullQueue

[setparsing]
REGEX = (?msi)^EventCode=(4624|4625|4634|4656|4659|4660)\D
DEST_KEY = queue
FORMAT = indexQueue

But, obviously, the events that matches one of the pruneusers, pruneusers or prunemachines AND matches the setparsing are indexed, while I would like that if an event matches one of the "prune" rules the event itself must NOT be indexed ... how can I do that?

Thank in advance

Have you tried putting setparsing after setnull and before prune...?
