Is there a policy or procedure to award an MOS based on civilian education (example: diesel certification for 91B)?

As a 12b, I deployed with a vertical construction company. On deployment, I trained 12w (carpentry and masonry specialist) and 12r (electrician) soldiers on their jobs, as well as performed them myself because of my civilian experience. I really hoped the commander would award me one or both MOSs, but didn't expect it, and didn't get either.

There used to be but required on the job trading at an MOS producing school.
Certain skill sets like construction trades, legal, medical,...........
It should still remain imho.

Medics can skip part of AIT training if they have EMT or paramedic certification. At least that was the case when I went to AIT.
