Only view warnings for one time step if it is similar in all time steps

Dear supporters,

I currently tried a NaN/Inf detection in my Simulink Model. For my purpose it is enough to get the position of the wrong input signal. Therefore I activated the NaN/Inf warning in the diagnostics. It almost works fine, the only problem i have now is that it displays roughly 16000 warnings, as my simulation runs through a loop and it detects the Inf/NaN in every single timestep. Is there a way to avoid this, so that it only tells me the warning once and doesn´t show up in the following time steps? I hope you understand my problem and that you can help me. If something is not clear, i can specify it more.

Thanks in advance.
