Management Reporter to add dimension columns in AX 2012?

Hi, I have used the Management Reporter wizard to create an Income statement.  While I am able to add one dimension.

Is it possible to show additional dimensions 

for e.g. BU and Cost Center. (I have accounting structure set up with these dimensions for P&L accounts in AX 2012)

how could we modify the date (that I set up using the wizard)? 

many thanks
