[Typo3] Tamplavoila unique DS for multiple TO

[keizo]

Hi,

I have made a DS in templavoila containing the elements for 2 or more TO.

In each TO object I map only wich i need for it.

The problem with this system, it's when i go to the page module and i 
create a new content element from my TO, i show all the element of the 
DS, not only the mapped for the TO selected.

Does anyone know how i can hide the DS element they are not used in a 
specific TO ?

Does exist a TS configuration var or a userFunc or a Local Processing 
(XML) hook ?

Thank at all
