You could try this through GeoPard without having to manipulate it in SMS. All supported under free trial account. 

1. Pull the sprayer operation directly from John Deere Operations Center into GeoPard. As-applied/application operations are imported through the JD integration:
   https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/import-precision-agriculture-data
2. Use the sprayer data to create/reclassify the coverage map, for example separating the areas by applied rate/product/tank mix:
   https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/zones-maps-and-analytics/create-a-zones-map-using-soil-yield-or-as-applied-data
3. Then there are two ways to send it back to Deere:

A. As a Map Layer: GeoPard can send any geospatial layer directly into Operations Center:
https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/john-deere-operations-center-integration/9.-export-soil-topography-satellite-or-analytics-as-map-layers

B. As an Application Operation: GeoPard can also export the processed map back into Operations Center as a John Deere Application Operation:
https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/john-deere-operations-center-integration/10.-export-application-operation-data-to-john-deere-ops-center

The remaining question is whether G4/G5 will let you select that Application Operation while actively harvesting. If Deere blocks it, then converting the tank-mix coverage into something Variety Locator recognizes would be the next workaround to test.

If you can share one example field/operation, happy to test the workflow.
