Grouping in Crystal Reports crosstab
===

I'm using Crystal Reports XI R2 and want to build a table using crosstab functionality to display some data. The trouble is I don't want grouping on rows, eg. I want all rows (except the period) to be displayed underneath each other and not one row be a subgroup of another) I want it to look like this:


    Period 1
           Group 1  value 1 | Summary field
           Group 1  value 2 | Summary field
           Group 1  value 3 | Summary field
           Group 2  value 1 | Summary field
           Group 2  value 2 | Summary field
           Group 3  value 1 | Summary field
           Group 3  value 2 | Summary field
           Group 3  value 3 | Summary field

    Period 2
           Group 1  value 1 | Summary field
           Group 1  value 2 | Summary field
           Group 1  value 3 | Summary field

    ...

Instead of this:

    Period 1
           Group 1 value 1 | Group 2 value 1 | Group 3 value 1 | Summary field 
                                             | Group 3 value 2 | Summary field 
                                             | Group 3 value 3 | Summary field 
                           | Group 2 value 2 | Group 3 value 1 | Summary field 
                                             | Group 3 value 2 | Summary field 
                                             | Group 3 value 3 | Summary field 
        
           Group 1 value 2 | Group 2 value 1 | Group 3 value 1 | Summary field 
                                             | Group 3 value 2 | Summary field 
                                             | Group 3 value 3 | Summary field 
                           | Group 2 value 2 | Group 3 value 1 | Summary field 
                                             | Group 3 value 2 | Summary field 
 
                                             | Group 3 value 3 | Summary field 
    Period 2
           Group 1 value 1 | Group 2 value 1 | Group 3 value 1 | Summary field 
                                             | Group 3 value 2 | Summary field 
                                             | Group 3 value 3 | Summary field 

    ...


Can this be achieved in Crystal Reports XI R2 using cross tabs?
