Is it possible to use the Metasound Builder Subsystem edit a Metasound Source asset? I’ve managed to batch-create Metasound Source assets just fine, but today I’m trying to create a tool that will simply Add Graph Input Node to an already existing Metasound Source. So far, I can’t figure out how to do this. Everything seems setup to only create Metasound assets, but not to edit one that already exists. Am I missing something here? Thanks for the help!
