Google Calander sync app

Any idea if Google sync will ever have a option for selecting the calender on the BB that is uses to sync? I am trying to keep my work and personal email seperate, so I need ot be able to sync my work calender via USB and want to keep my Google calender separate from my work calender.

Also, is there any way to show multiple calenders on the calender section of a today theme? Currently it is only displaying my default calender, so I can only show my work or my personal email not both
