EDI Schema - Change all the fields to optional

I would like someone help me if there is any built-in service to make all the edi schema (v4010 - 850) fields to optional from mandatory. This is on WM Version 10.5. We have our client sending edi file with only few fields as mandatory but the standard i created from the sef file has lot of mandatory fields.

I could get that done using the below 2 services by replacing all mandatory fields to false in the notepad editor.
