I have recently figured out how to import our local nutrien's as applied maps into my ops center account. I'd like to assign an accurate product rate to these as some were variable rate, others were flat rate. I've done this with spray, but i make a tank mix and apply it. The split bin spreader created two maps, one for potash and the other for MAP. However, after looking over the invoice it looks like it's a ratio they mixed for every field. So do i need to create a new product for each field each year? Or is there a better way?  I don't think i can just pick MAP or Potash as it looks like it's ways custom mixed.  Below are my invoice tickets's data.

2024 application I have a map for each of the following MAP and Potash for the same field.
