WinForms PropertyGrid with empty and non-empty Category

Question

Is there any way to customize Winforms PropertyGrid, if it needs to show one element without category on top (full row) and several categories with elements inside below?

using System;
using System.ComponentModel;
using System.Windows.Forms;
static class Program {
    [STAThread]
    static void Main() {
        Application.EnableVisualStyles();
        using (var form = new Form {
            Controls = {
                new PropertyGrid { Dock = DockStyle.Fill,
                    SelectedObject = new Test {
                        Foo = "one element without category",
                        Bar = "several categories",
                        Blip = "with elements",
                        Blap = "inside",
                        Blop = "below"
                    }}}}) {
            Application.Run(form);
        }
    }
}
class Test {
    [Category(" ")] public string Foo { get; set; }

    [Category("x")] public string Bar{ get; set; }
    [Category("x")] public string Blip { get; set; }

    [Category("y")] public string Blap { get; set; }
    [Category("y")] public string Blop { get; set; }
}
