Kotlin DSL read file outside of .teamcity directory

From my Kotlin DSL versioned settings, I want to load a metadata file that already exists and is used to manage deployment from outside of the .teamcity directory.

├──.teamcity
│   ├── Build_dsl.iml
│   ├── settings.kts
│   ├── pom.xml
├── kubernetes
    ├── clients.yaml

After finding the helpful comments on this bug I think I see that before the maven build is executed the .teamcity directory is copied to a temporary directory. I don't see any obvious way for the versioned settings Kotlin to access the kubernetes/clients.yaml file.

Am I missing something obvious that would allow me to do this or is this an unsupported use case?
