How to expose a struct type variable from dll, which is not declared [Serializable]

In my project I'm using a dll that contains a public struct like the following:
` public struct DLLStructName { public float SomeValue; } ` It is **not** declared `[Serializable]`. Now I'm declaring: ` public class MyClass { public DLLStructName structObject; } ` What I would like to achieve is that in the editor property view I can modify `DLLStructName.SomeValue`.
What is the best way to achieve this?
