I created a new PivotTable style and tried to define formatting for 4th Row
Subheadings. However, the number of Row Subheadings that you are able to set
seems to be limited to 3 (With cursor on the PivotTable menu Design,
right-click on a particular PivotTable Style and choose Modify (has to be a
custom style) - you can see all the PivotTable elements that you are able to
set formatting for). Is there a way to add additional elements? I can't
figure it out...

When I apply my style to the table with 4 levels of rows, 4th level gets the
same formatting at the 2nd level - go figure MS's logic behind that...

Any help solving this dilemma would be highly appreciated!
