BIRT Crosstab Column-Area Grand Total Repositioning

Migrateduser

<p>I need to place two of the columns in 'before' position and rest two in 'after' position. But I am forced to put them all together under Grand Total head either in 'before' or 'after' position. Please help me with any configuration to solve this or script for manipulating the columns positions in the cross-tab. Please refer attached.</p>
