The multilingual support always predict words in all languages, even if you started a sentence in a specific one. And it will follow the typo rules of the first language in the list. For example, if the first language is French, it will add a space before the interrogation mark (French rule), even if you're writing in English.

I'm wondering the same. Sure would be nice.

EDIT: And I found it a minute after my post lol. Inside Heliboard, go to settings, find languages, don't use system languages. Add your main language, then tap it and a "hidden" menu will come up. In it is the multilingual option. Tapping it will enable you to add another language to the same Heliboard language.
