multiple workers and google calendars

Hi, how can i add multiple google calendars, to each worker his own like bojan wrote in my other Support request? there is no such fields on the Profile of our wordpress (latest Version) for Google calendar api and key.

I am still not able to figure out why schedules do Show up on all our workers if they are just set to one of us.

Please see your self here:
