does the dataset.json need to point directly to anatomical files

[lundq163]

After generating my dataset.json file, the imagesTr path looks like this:
"training": [{"image": "./imagesTr/0mo_SynthSeg_generated_0000.nii.gz", "label": "./labelsTr/0mo_SynthSeg_generated_0000.nii.gz"...
the label file appears to be correct, but i was thinking the image file should be one of ./imagesTr/0mo_SynthSeg_generated_0000_000{0,1}.nii.gz
after running nnUNet, i dont seem to be getting any errors, but i am curious if this could potentially cause an issue i am unaware of

Note that i am using version 1
