There is a bit of a workaround for getting some NOTAMS while still on the ground. Make a flight plan with the airport(s) you want to check in it. While on the Flight Plan screen select Online Filing (don't worry, not filing with this step), then Options, then Get Briefing. Full briefing details with associated NOTAMS will be in the list. Click on Close Briefing, then Close Form, the Close to get back to the map.
