Data Composition Scheme Headings

I created a very good-looking report, but I have one problem: Data Composition Shows heading for all the fields I have added to the report. Some of the fields are groupings and some of the fields were joint together to make descriptions.
All that structure produces a lot of headings which I really want to hide. But I can not find how to stop showing heading for some fields or for grouping field. If I put Title = "" then the system stops showing data correctly.

The structure of the report is:
Company - date - detailed records

Detailed records:
Number
Group (Vert)
  Attribute
  Group (Horiz)
      Att1
      Att2
      Att3
......

Do you want to hide headings for fields while values should still be shown? Why? Can you show a screenshot of your report with what you desire to change marked?

You can try change Title of field into " " on pane "Data Sets", but it seems not, what you want.
