Scheduling for multiple calendars - synching schedules?

Scheduling for multiple calendars - synching schedules?

I work at two locations and am trying to figure out how to manage my calendars. Locations are within a block of each other and I'd like to be flexible about seeing patients at both locations on the same days. I'd like to put meetings and other times when I'm not available on both calendars without having to enter the information on both calendars separately (as well as my Google calendar). I have schedulers at one location but have to do my own scheduling for the other so everyone needs to be able to see my availability at each location.
Is there a short cut to this or will I just need to enter info twice?
Thank you!
