Dashboard Drilldown Query

Hello, I am trying to create a drill down chart from Pie to Column Chart but i am having problems. Data is coming from BW.
This is what my data looks like: (I have 2 queries defined in DD just by choosing fields differently).

Customer      Amount       Customer      Month/Year      Amount
1201                 100             1109              04/2014            100
1109                 200             1201              05/2014            100
1211                 300             1109              05/2014            100
                                            1211              03/2014            300

So as you can see I have 1109 customer in two months. Since my destination is set for row and only one row it only shows which ever comes first. Somehow I need to get my months like this in DD:

Customer      03/2014       04/2014       05/2014
1109                 100                                100
1201                                                        100
1211                 300

I changed my rows and column on BW side, but I have to choose those fields in Dashboard Design which puts them back in the shape that I drew at the top. I am basically trying to transpose but i don't know how to do that.

Please let me know if you have seen any issue like this and how you resolved it.

Thanks.
