Closed Feature: Modify XML coda before plublishing an update [196]

Hello,
Before, I used Local Update Publisher on Windows 2008 R2 WSUS.
I migrated my WSUS server on 2012 R2, and I changed for WSUS Package Publisher.

I'm trying to do the same think like in LUP : modify XML code (at the end of update creating) to publish a MSP update that have a bad development.
In LUP, I have just to modify XML language tag from 1031,1033,1036 to 1033 only

Is it possible to do it with WPP ?

Thanks in advance

Gregory
