EditorUtility.OpenFilePanel, select multiple files?

I can use EditorUtility.OpenFilePanel() to select one file, and EditorUtility.OpenFolderPanel() to select one folder, but how would I go about selecting multiple files in one panel instance?

OpenFilePanel returns a string, so it’s impossible to use it for multiple files. For that to work it would have to return a string array.
