Pytorch geometric Data Object

Is it possible to store two graphs in the PyTorch geometrics Data object?
Data(x=[B, 1100], edge_index=[B, 2, 4400], edge_attr=[B, 4400, 35], y=[B, 2])
where B=2 or B=1

In the official documentation, it has mentioned that the object should be as follows
Data(x=[1100], edge_index=[2, 4400], edge_attr=[4400, 35], y=[2])

Can someone clarify, I was trying to create a custom Dataloader.
