title: How to view text of merged cells when filtering another cell?
body: <p>The two columns look like on this image. </p>

  <p>When I want to show only the cells which contain a letter 'b', I can no longer see the text "Title1" and "Title2" which is normally visible in the column B.</p>

  <p>I guess although the cells in column B are merged, the text is still bound to A3, respectively to A7. </p>
  
  <p>So how can I at the same time filter the visible content and preserve the merged text? In simple words, I want to filter content by letter 'b' and I still want to see the text "title 1/2" in the column B. </p>
