I'm using the Piper addon in Home Assistant and want to have multiple voices for various usecases (one for assistant and one for security alerts, etc.). In the "Voice assistants" settings you can configure various personas for Assist to use and there are dropdowns for different voices too select when using Piper (see attached image). However, that dropdown only has a single voice which you configure in the Piper addon configuration. Is there a way to configure multiple voices to the Piper addon at the same time? I can only seem to get one working at a time.
