How to Remain the "id4" column in the Microsoft Terminology Collection File

Could anyone tell me how to create the term base using Microsoft Terminology Collection file with the IDs remained?

I saw there is the column of "id4" on the Microsoft Terminololgy Collection file and I want to use this numbers. However, when I convert that file using Glossary Converter, there is not listed in "Fields" and that IDs no longer exist on the converted XML file.

Best regards,
