Is it possible to output a NaN from the signal editor block?

I thought I had a signal editor outputting a signal which had NaN values for some parts. In a new model I tried to do it again but I only get an error that this is not allowed.
Is it possible to output a NaN from a signal editor and I just have some block/model settings wrong? Or did I imagine that I could do it before?
Thanks!

I don't exactly know which error your get, but maybe you just need to set the Diagnostic settings to not throw an error for NaN block outputs.

Hey Jonas,
Thanks for the suggestion and sorry my original post was lacking in specifics and probably not so clear. Here is the actual error I get on compilation (simulation doesn't start running):

I did try to play with that setting you suggested in the Data Validity menu but it only changes the warning/error behaviour during a simulation.
At the moment I have a temporary solution but it is not ideal, I thought that the signal editor block could output NaN before but I can't actually find any evidence of it working for me previously so I could be incorrectly remembering the prior behaviour :)
Here is my temporary solution with the second signal generator requesting NaNs (but it is not ideal for my use case):
