Schedule Travel Time on A Different Calendar than the original

CURRENT: Target Calendars selected will find scheduled events and adds travel time to the respective calendar.

REQUEST: schedule travel time onto a different subcalendar than the actual event

RATIONALE: I want travel time so automated bookings don't book over a meeting where I have to travel to it - but the travel events are making my calendar so cluttered that the events themselves don't stand out to me anymore and I don't have as clear a picture for what I'm doing each day.

Thanks!
