Yes, use the wizard, select Custom w/Complex Pole, and change

   

settings of Re and Im pole, lower Re, higher Im, cause greater

   

peaking.

Keep in min, in the time domain, a peaked or BP  filter will produce

   

some serious ringing if a complex frequency waveform is fed to

   

the filter, like a square wave..
