In parametric sweep, is it possible to use the eigenfrequency of last solution as the seed to the current eigenvalue problem?

Hi,

I'm doing a parametric sweep over some parameter (kx). For each value of kx, I trying to find one eigenfrequency. But my problem is that I want to use the solution for the previous value of kx as an input to the current value of kx.

Specifically, I want to use the value of the previous eigenfrequency as an input to the "search around frequency... " field of the eigenvalue solver for the current kx. Is this possible?

I know that you can use the previous solution as the initial value of the new solution but it doesn't let me specify the eigenfrequency of the previous solution as the initial guess of eigenfrequency of the new problem.

Thank you.
