Allow non camel case macro names?

1 
#[allow(non_camel_case_types)]
macro_rules! Foo! { ... }

IntelliJ still highlights this as a warning. I purposely want Foo! instead of foo! because this particular macro expands to something meant to be used as a Type signature.

Is there a way to tell say "hey, for this particular Macro, it is okay to have Uppercase" ?

The compiler doesn't emit any warning here. If it's an intellij specific error maybe there're some settings for it?
