Payload based message search for synchronous interfaces

Hi,

I am going through sdn to find out if User-Defined Message Search (UDMS) is possible to configure for synchronous messages in both ICO (AAE) and Classical (IE) scenarios. We are in PI 7.3. I know by default it is not supported. But I have seen this wiki:

http://wiki.sdn.sap.com/wiki/display/TechTSG/(PI)+User-defined+search+functionality+for+synchronous+messages

which talks about configuring UDMS for synchronous messages by logging them. But I think this wiki applies to PI 7.31 only. Can someone please confirm the same or if we can configure UDMS for synchronous messages in PI 7.3.

Regards,
