How to show custom DCL value using OOT Subject Area

Summary:

We notice that any custom DCL added in a standard Object is not reflecting in any OOTB SA, we are aware that OOTB SA is not editable and for us to see the Custom DCL is to create a custom SA that will includes the needed DCL. however majority of our users are using the OOTB SAs, just wondering is there a way we ca see the value of DCL without creating any CSA? like combing SA with the other SA? or any other method that will cater the said requirements aside from creating CSA?

we did the custom text field place holder as workaround but its not as effective as we wanted specially if the source changed its value,
