Alias in the QC

Hi, long time Kemper user here, but very much looking forward to September to get my QC.
Now, one thing that always annoyed me with the KPA is the aliasing effect - if you have an heavily distorted sound, and send the poweramp signal (so, no cab sim) to a guitar speaker, you’ll that disgusting aliasing effect (when you’re playing the highest notes, of course).
The thing that I never quite understood is: is it so hard to just filter out the highest harmonics that can’t be DA converted on the outputs? Maybe I am missing some technical difficulty about that.
Well, if there’s no such difficulty, I hope this will be implemented in the QC, because c’mon, the world is full of metalheads cranking up their gain =D
