Compositing UI feedback if File Output won't write.

Granted this is more of an issue for me as I'm hopping between several machines with different drive letters.

But when I open a project created with File Output in compositor writing to F:... on a machine with no F drive, blender will render as normal, but won't write the files. Now I still have access to my PNG seq in C:\tmp\ but compositor is where I organise my Multichannel EXRs.

Perhaps a pop up, "Hey your're a fool, check your output path" but even a warning icon like Geo Nodes has whenever the inputs to a node make no sense.
