[TYPO3-english] Allow BE users access only parts of TemplaVoila's DS

[Victor Livakovsky]

Hi, list.

We have a website, which has 5 content areas in TV page module and I need to 
create a BE usergroup, which needs to add and edit contents of only 4 of 
these 5 areas.
How can I implement such a functionality?

TYPO3 4.3.3
TV 1.4.4

Thank you in advance for responces.
