How Best to Import Piano MIDI?

Hi, Folks. Long-time SONAR user; noob Notion user. Rather than exhaustively reciting everything I've tried, and the obstacles I've encountered, I'll just ask if someone can give me a brief outline in broad strokes of how best to do this:
Suppose I have a nicely quantized solo piano performance saved as a Type 1 MIDI file with the right-hand part on track 1, and the left-hand part on track 2. How can I most quickly and easily get this imported to Notion as a single grand staff with the two parts in their respective clefs?
Thanks,
Dave
