I have created a validation rule in Core DB, and I have created a custom Sitecore field called 'Single Select Treelist'. I want to apply this validation rule to all 'Single Select Treelist' fields in all templates in my Sitecore instance.
I know we can individually apply the validation rule to each template field of type 'Single Select Treelist'. Is there a way to achieve this automatically for all 'Single Select Treelist' fields without any custom coding?

I see the list of field type validation rules available in Master:

How are these connected to the respective field types in Core?
