WSL　:　実行可能ファイルでも拡張子ごとに色分け

実現したいこと

WSL上で実行可能ファイルであっても拡張子ごとに色分けしてlsコマンドで表示したい。

質問

WSLでubuntuを使っているのですが、/mnt　以下のファイルは全て実行可能ファイルとして全て緑で表示されてしまいます。ファイル数が多くとても見ずらいため、実行可能ファイルであっても拡張子ごとに色分けして表示させたいです。どのようにしたらよいでしょうか。
以下に貼り付けたdircolorsの最も下にある”EXEC”のオプションが実行可能ファイルの色を決めていると思うのですが、このオプションを付けてもつけなくても色が統一されてしまいます。
