Is there a way to use the symbol 'hh' in the Japanese voice bank?

I’m really curious. Voice banks in English and Chinese can give you the feeling of exhaling when you write the “hh” symbol, but somehow you can’t write the “hh” symbol in Japanese voice banks. Please let me know if there is any way to use hh symbols in the Japanese voice bank.

I think just trying “.h” should get you the results you want?

Thank you so much. It was solved thanks to you!
