How can I stop ReSharper from adding an unwanted newline after a line preceded by a comment?

I sometimes use comments to "group" members like this:

// unary operators:
 public static readonly string Not = Create(nameof(Not));
 public static readonly string Negate = Create(nameof(Negate), "-");

// mathematical operators:
 public static readonly string Add = Create(nameof(Add), "+");
 public static readonly string Subtract = Create(nameof(Subtract), "-");

Quick format will insert a newline after the line that is preceded by a comment:

// unary operators:
 public static readonly string Not = Create(nameof(Not));

public static readonly string Negate = Create(nameof(Negate), "-");

// mathematical operators:
 public static readonly string Add = Create(nameof(Add), "+");

public static readonly string Subtract = Create(nameof(Subtract), "-");

Where do I turn this off?

To me it makes sense for ReSharper to insert such a newline if the comment were an XML doc (`/// <summary>...`), but for regular comments (only two slashes) I don't want that.

I'd rather turn it off altogether if there is no separate option for two-slash comments.
