Where can I obtain Army Warrant Officer Trend Reports?

Good morning.

After searching through milSuite, Rally Point and a few other sites, I cannot locate any trend reports for warrant officers. While I have found force strength numbers, the specifics I'm looking for cannot be found. At one point in time, I had a mentor who has since retired. He would always send me reports of 140 series warrant officers and what schools/education/duty positions/etc those getting promoted would have.

With that being said, can anyone point me in the right direction for obtaining Warrant Officer trend reports (specifically 140 series)?

Thanks
