EDIFACT Control Number override parameters are not unique

Hello Team,

In our current implementation, we are attempting to override the EDIFACT control numbers present in both the UNB and UNH segments. However, through investigation with the PMR, we discovered that the Override parameters are being reused from the EDI Parameters, which leads to inconsistencies across different message formats.

Issue:
The reuse of these override parameters from the EDI Parameter causes confusion and makes it difficult to accurately track and manage the control numbers across various EDIFACT messages. This inconsistency results in complications when attempting to override the control numbers, as the parameters do not provide a clear distinction between different message types or segments.

Enhancement Request:
We propose the introduction of a unique parameter specifically for overriding the EDIFACT control numbers. By having a dedicated parameter for control numbers, it would become significantly easier to identify and manage overrides specific to the UNB and UNH segments.

Also these EDIFACT parameters are not updated in the ITXA official documentation

Thanks.
