The recommended way to construct a pipeline for internal use is 'Pipeline::makePipeline'. However, at the time of writing, this method doesn't support specifying any aggregate command options. This ticket tracks the work to support specifying aggregate options to Pipeline::makePipeline.

As an implementation note, this will likely involve plumbing aggregate options through 'attachCursorSourceToPipeline' so that they are available at the time of executor creation.
