I've been creating planting prescriptions for years and everything works great............not this year!  GRRRR.
Planter has a triple Rawson drive, run by the AgLeader Insight, version 8 if I remember right.  Planting prescription will only control 1 channel/drive, not all three.  AgLeader "help" says I need to make a multi-product/multi-layer prescription.

OK, but I can't find any instructions how to do it.

Can anyone "show me the light"?  Need to get new prescriptions made ASAP.

Thanks!
