Terminology_id versioning

I am currently struggling with having the version of codesystem inside the repository.
By default the teminology_id just has only Value, as <defining_code><terminology_id><value>ICD-10</value></terminology_id><code_string>M720</code_string></defining_code>

But I would like to have the version as well as <defining_code><terminology_id><value>ICD-10</value><version>2021</version></terminology_id><code_string>M720</code_string></defining_code>

I tried in the archetype designer, but with no success. I am using Better’s openEHR Platform.

Could this be something that is hard coded and I cannot modify by myself?

Any guidance on how I can proceed with this, is appreciated.

Thank you.

Michael
