NWBC 5.0 changing message on Index page

Hello together

As in mentioned in Post NWBC 4.0 changing message on Index page it is possible in NWBC 5.0 Desktop PL2 to change the welcome message also?

We themed the Indexpage with the Theme Designer (Version 1.6.0, delivered with SAP_UI SP10)  and use the "/sap/bc/ui2/nwbc".

The Table "NWBC_CFG" is defined as follows:

IDX      COCKPIT      NAME                           LANG      VALUE

001      *                  WELCOME_MESSAGE     *          Willkommen &FULL_NAME&

Nothing happend. The welcome message is the same as before (see attachment).

Any solution to write a personal welcome message in NWBC Desktop Client 5.0 with the new ui2?

many thanks!
