Amtrak Guest Rewards - Add Amtrak Reservation to Calendar

Sorry if this has been asked previously:

Is there any way to automatically add an Amtrak reservation to my outlook/ical calendar?

When you make a reservation using the iOS app, there is an option to add it to the calendar.

I use tripit.com and it scans my inbox an automatically enters all my amtrak reservations (as well as other travel information) into my calendar.

Thanks for the assistance!
