ActiveSync and multiple Addressbooks/Calendars

[Henne Holly]

Hi,

in the ActiveSync settings in roundcube I can mark multiple 
calendars/addressbooks for syncing. But my activesync client knows 
nothing about different calendars, right?
So ActiveSync pulls every calendar, marked for syncing in roundcube, to 
one single calendar on my mobile device. If I create a new item there, 
where does it get stored? Is there a way to put it in a specific calendar?

regards,
Henning
