Crosstab subtotals in JasperSoft Studio 5.5

[drummer54]

I've asked a similar question and received no responses but have made progress - albeit by trial and error and creating a new report each time I figure something out with row groups, because there seems to be no facility for rearranging crosstab row groups.  The current issue is that the highest level row group - year - produces only a total row at the end of the report even though there are, depending on one of the parameters being passed, sometimes multiple years to display on the report.

In the attached XLS file search 'Total January'.  Under that row there should be a row labeled 'Total 2014', but instead it goes into December 2013 and at the end of the report there is a row labeled 'Total 2013' which combines all of the data for 2013 and 2014.  How can this be resolved?  And can it be done without creating yet another report from scratch that would include the fix?  As stated above, if the answer it another row group that is parent to the year group, there seems to be no way to add it, because it will be appended to the other groups and there is no way to move it.
