Can I use a param as a default for another param in a pipeline?

[e-gineer]

I'd like to do this:

pipeline "approve" {

  param "prompt" {
    default = "Do you approve?"
  }

  param "subject" {
    default = param.prompt
  }

  // ...

}

But I get this parse error:

2024-03-14 16:17:46 [flowpipe] error Failed watching workspace for mod mod.approval: failed to reload workspace: Bad Request: Failed to resolve dependencies after 2 passes. Unresolved blocks:
   pipeline.test -> pipeline.approve
   pipeline.approve -> param.prompt
     MISSING: param.prompt
