Using a meta sound within meta sound preset, sound class doesn't work

When creating and using a meta sound as a preset within a meta sound, the sound class of the meta sound used as a preset is not applied.

Pleas how can i set a sound class in a meta sound.

A = Create and attach Sound Class ‘SC_A’
B = Create and attach Sound Class ‘SC_B’

→ In this case, ‘SC_B’ doesn’t work.

I am no Metasound expert, but I don’t think this is possible. For this to work, the audio would need to go from Metasound to audio class and then from the audio class back into the Metasound. I think that the audio class stuff is a completely separate system that is applied after Metasound processing.
