Can I have H2 autocreate a schema in an in-memory database?

(I've already seen the H2 database In memory - Init schema via Spring/Hibernate question; it is not applicable here.)

I'd like to know if there's a setting in H2 that will allow me to auto-create a schema upon connecting to it. If it helps, I'm only interested in the in-memory case.

H2 supports various semicolon-separated modifiers at the end of the URL, but I didn't find one for automatically creating a schema. Is there such a feature?
