Alternative for __getitem__ method of Dataset in LightningDataModule

Hi, this is a very great framework. I was wondering in we can edit the getitem method in the custom dataset. I could not find anything in LightningDataModule. Is there any way to do that?

LightningDataModule just holds your dataloaders. You still need to use native PyTorch Dataset/Dataloaders to work with data.
