CST MWS Farfield help

Hi Everyone,

I am new to CST MWS. I simulated a standard gain horn antenna. But in the 'Field Monitor' option, I forgot give the 'far-field parameter' for a particular frequency. Without running the simulation again, Is there any option to get the radiation pattern ? (To see the far-field pattern of the added frequency, I have to simulate once more that model !... But i don't want that )

Please help me.
Regards,
Ubabmar.
