Google Calendar - Change Default Activity Type

The current default for the activity types that are created by the google calendar integration on the home page is “Meeting”.  Unfortunately, that is an inactive activity type for us and not one we want to use.  We would like the default to be one we have called “External Meeting”.   We would like a configuration to determine what the default should be.  Even better would be have filters to define what the default should be.  For example, if all the attendees have an internal domain email, then make the default “Internal Meeting”.  If any have an external domain, then make it “External Meeting”.
