Will there be a plan to make ElevenLabs v3 (voice engine) an option when using HeyGen's streaming API?

When creating videos using "Create in AI Studio," I can select ElevenLabs v3 as the Voice Engine, and there are no problems with Japanese intonation.

However, I cannot select ElevenLabs v3 with the Streaming API, and I'm concerned about misreading of Japanese kanji and unnatural intonation.

Eleven_flash_v2_5 and eleven_multilingual_v2 were not equivalent to ElevenLabs v3.

When using the Streaming API, is there a way to read Japanese characters as correctly as ElevenLabs v3 and improve intonation?

My current settings are listed below.
