Is it possible to fuzz Rust repos with multiple fuzz folders?

[Manishearth]

ICU4X is a single repo, but it has multiple "component" crates, some of which have fuzzers (e.g https://github.com/unicode-org/icu4x/tree/main/components/calendar/fuzz).

It seems like for a Rust project to work with OSS-fuzz, it needs to have a single toplevel fuzz directory, according to the docs.

Is it possible to configure a Rust project to have multiple sub-fuzz folders??
