@WithSpan class level support

[KimDoubleB]

Hello.
I'm using opentelemetry in Spring boot and WithSpan annotation for Feign support.
@WithSpan annotation only supports per method, so I have to add the annotation to each method of my Feign implementation to use it.

This is inconvenient and seems to be a point that can be missed during development,
so I'm currently implementing an annotation that does something similar at the class level.
It works, but I don't think it's good in terms of maintenance.

Is there anything like @WithSpan annotation that works as AOP on the class level?
Or are there any plans to make the @WithSpan annotation applicable on the class level?
