Default [Q] multiple calendars

Folks

I have got 3 separate Google Calenders all sync to the I9000 as a single calendar which works well.

However what I would like to do is to separate 2 of the calendars
e.g Personal and business

I believe if you go in to the Calendar and select menu there should be a option MORE to allow you to split out the calendars.

I don't see this option.
Any idea's ?

FYI
Samsung I9000
Gingerbread XXJVK (2.3.3)
