How to transform a nested case class to another nested case which has one extra field inside the nested class using chimney in scala

Question

package a

final case class mySettings(multicache: myCacheSetting, defaultTtlHours: Duration)

final case class myCacheSetting(
    weightedRoundrobin: InternalWRRMultiCacheSetting,
    attempts: Int,
    clusters: Seq[MyClusterSetting]
)

final case class MyClusterSetting(id: String, settings: InternalMyClientSettings)

final case class InternalMyClientSettings(
    user: String,
    environment: Option[InternalMyClientEnvironmentSettings]
)

final case class InternalMyClientEnvironmentSettings(
    socketTimeout: Option[FiniteDuration],
    connectTimeout: Option[FiniteDuration],
)
final case class InternalWRRMultiCacheSetting(maxWeight: Int, incrementWeight: Int, decrementWeight: Int)

This class needs to be converted into

package b

final case class mySettings(multicache: myCacheSetting, defaultTtlHours: Duration)

final case class myCacheSetting(
    weightedRoundrobin: InternalWRRMultiCacheSetting,
    attempts: Int,
    clusters: Seq[MyClusterSetting]
)

final case class MyClusterSetting(id: String, settings: InternalMyClientSettings)

final case class InternalMyClientSettings(
    user: String,
    company: String,
    environment: Option[InternalMyClientEnvironmentSettings]
)

final case class InternalMyClientEnvironmentSettings(
    socketTimeout: Option[FiniteDuration],
    connectTimeout: Option[FiniteDuration],
)
final case class InternalWRRMultiCacheSetting(maxWeight: Int, incrementWeight: Int, decrementWeight: Int)

as you can see both classes are almost similar except that the second class contains an additional field company. company needs to be filled with a constant.

A explaination on how you found the solution will be appreciated

I tried using into and transformInfo from scalaland:chimney but it didnt help. The missing field is causing a lot of issues while transforming
