Is it possible to make assistant overrides to the transcribel model and language used? I tried doing it via a tool that gives back assistent override json as result but it doesn't actually change it. My goal here is to have a multilingual agent (NL-ENG). But when I use nova-3-general and multi, when the conversation is in dutch it struggles sometimes because it will think the caller is saying words in english when they're not, causing the conversation to be bad. I have seen people use dtmf in combination with the first_message (press one for english. Hoi dit is de assistent.. (continues in NL)), but I can't get dtmf to work, the input is never captured. And even if it is I'm not sure what the follow up is (an override (how!) or squad logic), when you press one it is silent for only 1-2s and then he continues in English. Anyone has trick/tip on the best way to set it up? Ideally I want the transcriber model to be on nl when convo is dutch and on en when english
