Can I add an entry in my gmail calendar and 'invite' the team calendar in confluence?

[Nina Hoven]

I'd like our staff to be able to enter an appointment in their own gmail calendar (as its what they use) and invite the team calendar, rather than having to enter it twice. Is that possible?

I know we can subscribe to the team calendar from our gmail but I want to know if we can do it the opposite way as well. 

Many thanks.
