How to reset the _TCP_ROUTING dest key

Please assume the below in transforms.conf

[send_rawevents]
REGEX = .
DEST_KEY = _TCP_ROUTING
FORMAT = indexer1

[send_to_null_tcp]
REGEX = CEF\:0\|ids
DEST_KEY = _TCP_ROUTING
FORMAT = nothing

[send_to_syslog]
REGEX = CEF\:0\|ids
DEST_KEY = _SYSLOG_ROUTING
FORMAT = syslog_group

The objective here is to send all event to the tcp out unless they match the regex CEF:0|ids in which case events should be sent to the syslog out.

What I can't sort out is how to reset the _TCP_ROUTING back to nothing in those events that are routed to syslog (since I don't want to have them duplicated).

Anyone has any idea here ?

Thanks !
