[TYPO3-english] multilanguage - multitree with TV

[G.Unger]

hi group

Posted this in templavoila group, but here it might be good as well to ask?!

I have a question concerning the templavoila localisation.

our tree concept looks like this

website
   ch - branch for the swiss with 4 languages default en + it fr de
   int - international branch with 1 language default en
   lam - south american tree with 3 languages default en + pt sp

so we do have 6 languages

en = 0 = default for all trees/branches
de
fr
it
sp
pt

while that latest 5 are not for all trees/branches

I have of cause created the languages on the worldbowl as alternative 
page language.
the declarations eg

config.sys_language_uid
config.metaCharset
config.locale_all
config.language

all are all set and templavoila and realurl all workz well.

the only problem/hook I have is that in the page module of templavoila 
for me as an admin appear all languages in the top tab 'localisation 
view' and in the dropdown 'Create new page translation:' all languages 
appear.

how can I limit by TS (? template or page TSconfig) that only the 
equivalent languages per branch appear in TV localisation?

kind of stuck on a possibly small tweak :(
