FEMM currently doesn't have a built-in way of doing this. It wouldn't be that difficult to add this functionality. However, the reason that I didn't design this in is because the peak values are often not very meaningful. Around corners in permeable material, the solution can be nearly singular--the exact peak value has a strong dependence on local mesh density.
