Adding dummy elements to the layout

Hi,

I started my layout design and for the matching purpose, I need to add dummy elements like transistors, resistors. whenever I add an instance as a dummy in the layout the LVS will complain that this element doesn't match to the schematic, Then I need to put that instance in the schematic as well, but this procedure makes my design longer.

I believe that there is some tool in Cadence Layout XL that is concerned with adding dummy elements and I hope you could help me with. Or if there is no such tool then at least how to ignore elements in the Layout from LVS

Thanks
