Is there no way to get the different calendars inside of Zoho Calendar to all sync back to the calendar inside of the CRM?

For example.  I have Followup.cc that shows up in my Zoho Calendar, as well as personal and business calendar.  But I have to manually enter a task or meeting inside of the CRM to see anything.  Nothing syncs back to it from Zoho Calendar.

I'd like the business calendar and Followup.cc to both show up in the CRM, as well as anything I manually input inside of the CRM calendar.  

This way my team knows what I have on my schedule.  Please let me know if there's any way to do this.  Thanks!
