WindowsForm - How to add two DataGridViewButtonCell on the same cell?

Is it possible to add two buttons of type DataGridViewButtonCell in the same cell in a DataGridView? I researched a lot and so far I could not find any solution.

Edit 1: For example, I wanted to add a button [Morning] and another [Late] on the same cell ... I tried to add a panel, but it does not accept because the DataGridViewButtonCell is not a Control type.

Edit 2: This is what I can do today ...

Anyway,theproblemcomesupwhenIselectonelineandthenIselectanother.ItlookslikeRectangleisinvisible...Ex:

Eventcode:

reservaGrid_Grid.CellPainting+=(sender,e)=>{if(e.ColumnIndex==-1&&e.RowIndex>-1){//exibeasdatasemcimadascolunas,desenhandodeduasemduaslinhasfor(inti=0;i<reservaGrid_Grid.RowCount;i+=2){stringquarto=string.Format("Quarto: {0}", Funcoes.String.FindStringAfterCharacter(reservaGrid_Grid.Rows[i].Tag.ToString(), '_') );

                    Rectangle retangulo     = reservaGrid_Grid.GetCellDisplayRectangle(-1, i, false);
                    //int largura           = reservaGrid_Grid.GetCellDisplayRectangle(-1, i + 1, true).Width;
                    retangulo.X             += 1;
                    retangulo.Y             += 1;
                    retangulo.Width         = retangulo.Width / 2 + 15;//largura do header
                    retangulo.Height        = retangulo.Height;//tamanho do header, preenche 2 linhas
                    StringFormat format     = new StringFormat();
                    format.Alignment        = StringAlignment.Center;
                    format.LineAlignment    = StringAlignment.Center;

                    //pinta o fundo do retangulo
                    e.Graphics.FillRectangle(
                        new SolidBrush(
                            reservaGrid_Grid.ColumnHeadersDefaultCellStyle.BackColor
                        ),
                        retangulo
                    );

                    //desenha a string no retangulo
                    e.Graphics.DrawString(
                        quarto,
                        new Font(reservaGrid_Grid.ColumnHeadersDefaultCellStyle.Font.FontFamily, 13, FontStyle.Bold),
                        new SolidBrush(reservaGrid_Grid.ColumnHeadersDefaultCellStyle.ForeColor),
                        retangulo,
                        format
                    );
                }
            }
            //reservaGrid_Grid.Invalidate();
        };

Why will it be?
