Adding fields to check report in Ax 2012

Hello All,

I am customizing the cheque report, here I want to add some new fields(Not on the cheque, only to invoices) and realign the existing invoice line fields. But for this report in the Visual studio design, I can only see [SlipTxt] doing all this, How can I achieve?

I have already tried with new temptable, Its working fine, But can't achieve the design(Standard).Is it possible to do with the existing design?
