How to customize the mapping between shotgun entities and RV "Entity Fields"

Hi, is there any documentation to look up for this question? I saw another similar post here: How do I modify Shotgun Info (shift + i) menu in RV? - #2 by Greg_Naud
This could be a very helpful feature. Because we have our own shot cut update workflow, meanning we are having lots of omitted shots on daily basis.
Thanks for any potential help!
