How to get patches coordinates from RandCropByPosNegLabeld?

[OeslleLucena]

Is there a way I can get the coordinates for all patches sampled from RandCropByPosNegLabeld?
After the forward pass, I can see that the batch dict has image_meta_dict and label_meta_dict but I cannot find the coordinates from the sampled patches. I tried batch['image_meta_dict']['slice_start']) and batch['image_meta_dict']['slice_end'] but I get [0,0,0,0] from both.

The centres of the segmentations are stored within the class, but aren't returned to the user: https://github.com/Project-MONAI/MONAI/blob/master/monai/transforms/croppad/array.py#L607. This seems like it would be an easy modification to make. Feel free to create an issue as a feature request and I'll have a look at it.
