Figure out which parts of a batch calculation with structfun produces a warning?

If I use a command that performs calculations on several cells or arrays or fields of a structure at the same time and some of those calculations results in matlab producing a warning, is there any way that I can find out from which of the calculations the errors originates from?
Example: Say I use structfun to estimate several regression models in one call like this:
models = structfun(@(x) fitlm(x,Ytrain,'linear'), Xtrain, 'UniformOutput', false);
And some of those estimations produce a rank deficiency warning. How can I figure out afterwards which fields in the structure produced the warnings so I can treat them differently?
