How to create user defined Nature of transaction code for Intrastat transactions

Summary:

Hi All,

I've created a rule for a Nature of Transaction code specific to a particular legal entity, and I have added a user-provided values. However, in the actual Intrastat transactions, I'm noticing several other values that are unnecessary for the report. The users only desire to see in the dropdown those values they have provided. Please refer to the attachment.

I have configured below set up in order to achieve the requirements.

1st Set Up - Intrastat rule (Transaction Code rule)

2nd Ste up -Intrastat Parameter (Defined based on legal Entity),

User want only selected values given by them and also they want translation to be available in Slovak and Czech. Please advise.
