How to get plot Exclusions for a numerical function?

I have a complex analytic function that I'm computing numerically, and it has branch cuts along arbitrary curves that I can't know beforehand. Does anyone have any ideas on how I can get Exclusions- like functionality from Plot3D for this case? With the allowed form "Exclusions -> {{lhs = rhs, ineqs}, ...}", I can't think of an easy way to do it numerically... maybe something like "Exclusions -> {{True, <something clever>}}"? Has anyone tackled this problem before?
