MONAI's Compose output filename

1

Hi,
I would like to edit the name after defining a @MONAI transform, as below.
I would like for run transform in a for loop. Is it possible to edit the name of the output file, before applying transform? ?
Thank you,
fp

from monai.transforms import (
    AddChannel,
    Compose,
    EnsureType,
    LoadImage,
    NormalizeIntensity,
    RandRotate90,
    RandSpatialCrop,
    SaveImage,
)

transform = Compose(
    [
        LoadImage(image_only=True),
        NormalizeIntensity(),
        AddChannel(),
        RandSpatialCrop((128, 128, 128), random_size=False),
        RandRotate90(prob=0.5, spatial_axes=(0, 1)),
        EnsureType(),
        SaveImage(
            output_postfix="postfix",
            output_ext=".nii",
            resample=False,
            separate_folder=False,
            print_log=False,
        ),
    ]
)
