This is not possible out of the box. It is possible to implement a generic way of accessing properties like this via reflection but that will be a huge performance penalty to your project and is therefore not recommended. If you are still willing to use such an approach despite the performance penalties please do let me know and I will prepare a small sample for you on how this can be achieved.
