Is there a way to plot cutoff frequency versus control voltage in Multisim 11?

I'm trying to model a voltage controlled low-pass filter part of a synthesizer. I have a DC control voltage feeding into my filter and an AC voltage source as an input to the filter. I want to plot the -3dB cutoff frequency of the output of the filter (vertical axis) versus the control voltage (horizontal axis). I figured I could do a DC sweep and for the output enter in an expression but I don't see a way to determine the cutoff frequency using the expressions available.

Run the Parameter sweep analysis and sweep the DC source, under the "More Options" select "AC Analysis"  When you run the analysis, you will get several frequency response plots and on each plot find the -3db point using the cursor  and then manually enter the value is a table, you will have Excel to plot DC vs. -3db frequency.

Thanks! This helped a lot! I didn't know it was possible to sweep two different parameters at once and plot all the results on a single graph. This will save a lot of time in the future for sure.
