[TYPO3-templavoila] Change the Language of all Flexform elements to "all" < automaticly?

[Jens Hoffmann]

Hy TV Freaks,

I have a small Question:

Is there a way to tell all FCEs that
they should have a default Language setting,
set to "all" (which is -1) ?

I tryed this as PageTS ...

TCEFORM.tt_content.sys_language_uid.types.templavoila_pi1.default = -1

... but this can't work :(

I really need help in this one.

THX in front.
