How can I create a Macro for adding full Eventbrite descriptions to Google Calendar entries?

Eventbrite makes it easy to add events to google calendar, but these entries do not include the full event description.

I'm trying to use Keyboard Maestro to include the full event description in the google calendar event details. I know how this would be achieved in Authohotkey but am unsure where to start with Keyboard Maestro. I was wondering if any of you helpful folk might have any good suggestions?
