Multiple Designs for different companies

Hi Experts,

I have created a new design for the report PurchPurchaseOrder (Purchase order confirmation report). I need to print the new design in a particular company only. I am aware that PurchPurchaseOrder report uses printmanagement but no idea where to place the condition; should be in PrintMgmtDocType class or PrintMgmtReportFormat table etc. and how the condition should be, in case of different companies.

Please help. 

Thanks
