[OpenMesh] Store/Restore custom property of type 'vector<T>' with dynamic size?

Hi, OpenMesh has implemented the functionalities to s/r custom property of vector<T> in OpenMesh/Core/IO/SR_binary_vector_of_fundamentals.inl. However it seems to expect the size to be known in advance when restoring. Is there a way to restore the size dynamically? I think maybe it's better to store the size as well? Kind regards
