Dividing one big enum in multiple small enums. Can strum still be derived?

[KSXGitHub]

Sometimes, there are use case that require many variants, so for readability, I want to divide the enum into multiple small enums. Like this:

#[derive(AsRefStr, Display, EnumCount, EnumIter, EnumString, EnumVariantNames, IntoStaticStr)]
#[strum(use_phf)]
enum MainEnum {
    FirstCategory(FirstCategory),
    SecondCategory(SecondCategory),
    /* ... */
}

#[derive(AsRefStr, Display, EnumCount, EnumIter, EnumString, EnumVariantNames, IntoStaticStr)]
#[strum(use_phf)]
enum FirstCategory {
    Foo,
    Bar,
    /* ... */
}

#[derive(AsRefStr, Display, EnumCount, EnumIter, EnumString, EnumVariantNames, IntoStaticStr)]
#[strum(use_phf)]
enum SecondCategory {
    /* ... */
}

/* ... */

let value: MainEnum = "Foo".try_into().unwrap();
