smart parametric sweep?

I was wondering if in Parametric sweep it is possible to update Study Settings based on the up-to-date results of the computation (i.e. based on the results computed from the previous step of the sweep)?
For instance, I want to use parametric sweep to trace the dispersion of a fibre mode. I can use frequency as parameter. For each frequency I want to compute mode effective index. I use Mode Analysis study for this purpose. In the study setting I need to specify the initial guess for the effective index (specifically, it says: "search for modes around ..."). I can put there some number which is fine as initial guess for the INITIAL frequency. But, as frequency changes, the effective index changes as well. It would be wise to substitute effective index computed in the previous step. In this way Comsol could easily trace the mode. However I cannot see how to do this?

I have the exact same problem, did you manage to fix it?
Thanks,
