Custom Fields not on Core

Hello!
I used your plugin to fix some checkout fields incorrections and added some new fields. They are working, although, when looking at the Woocomerce Orders page, they appear as Custom Fields, outside the “core” fields of the Woocommerce checkout. I really need them to be alongside the default fields, not as “extras”.
Is there a way to make these fields part of the “core fields” at the Woocommerce Orders page?
