はじめに
マルチシーンで作っている時に毎回、プロジェクトを開く度にHierarychyにシーンを追加するのが面倒だったのでBuild Settingsと同じシーンを一気に開けるようにしました。
スクリプト
プロジェクトにEditorフォルダを作り、以下のスクリプトを配置するだけです。
Unity2018.3.6f1で動作確認しました。

解説
大した事はしていませんが、プロジェクトを開いたときに実行するInitializeOnLoadMethodAttributeとプロジェクトロード完了時に実行するEditorApplication.projectWasLoadedを組み合わせてBuild Settingsに設定したシーンを開いています。
