Using nested attributes from linked objects in index definitions

Hi all,

I have a question regarding the use of nested attributes from linked objects when defining indexes.

In my model, I have an object Cement that has a direct link to another object called ScenarioContent.

I would like to use the attribute ScenarioContent.Type as part of the index on the Cement object.

This is particularly useful, because I use views that filter Cement instances based on ScenarioContent.Type.
 For example, to expose only planned scenarios, I use the following rawFilter in a view:

@view(
  rawFilter: {
    nested: {
      scope: ["Cement", "ScenarioContent"]
      filter: {
        equals: {
          property: ["ScenarioContent", "Type"]
          value: "PLANNED"
        }
      }
    }
  }
)

Question:

Can I use this nested attribute (ScenarioContent.Type) in the index definition of Cement?

If this is not currently supported, is there a recommended alternative to support performant queries on this kind of filter?
