Multiple asian languages in one presentation.

Is it possible to use multiple language in one presentation?

- [EN+TH+JP] in one presentation -
let’s say I have a presentation that the header is written in English but the content is in Thai and a subtitle below my content is in Japanese

For now changing theme are only allow me to use 2 languages at once(EN+TH, EN+JP, EN+CN and so on).

so… is it possible to use multiple language in one presentation?

Thank you.
