set up optimization in ads

is it possible to set up the goal and optimization for multiband circuits in ADS? I am using ADS 2008 and am designing a LNA at 2.4 and 5.25 GHz. I am using the transmission line equivalents of lumped elements in the matching network so I need to optimize the lengths and widths of the transmission lines. I can setup the optimization at one frequency but it will degrade the response at the 2nd freq. so is there anyway to run optimization at both the frequencies simultaneously? If yes, I'd be grateful if someone could tell me how or maybe give a link to a tutorial or something...thnx

Yes.

Put another goal with varied frequency range.

thnx fr the reply...does the same apply to a mixer too? I mean can I set the optimization for the conversion gain parameter in both the frequency ranges? another question is, how do I give the input frequencies? I mean the P_n tone source generates both the frequencies simultaneously but since my architecture is not concurrent only one frequency will be input at a time...so how should I set tht up?

also, for the mixer since the IF is kept the same for both the incoming frequencies by varying the LO as well is it possible to run the optimization?
