Help with Nordictrack x24

[mtbraun]

My old x12 finally gave up the ghost. It was 15 years old so I was pretty happy with what we got out of it. I only use my dreadmill for specific incline training and defined interval workouts. I didn't do much research into the replacement and bought an x24. The treadmill is fine, but the ifit app is just terrible. I'm having trouble building a custom interval workout from Training Peaks. Since there is no connection between the two I need to build this manually on the treadmill. I see where to build a manual workout but cannot figure out how to start with a warmup, add the intervals, add a zone 2-3 segment, then a cool down. I got angry and just walked away. Hoping someone can help me out. Thank you.
