can we choose how numbers are formatted when exporting reindexed datasets

[ganindu7]

for example

my_dataset.transform("reindex", start=0)
my_dataset.export(exportPath, format="cvat", save_media=True, image_ext=".png")

would create images with indexes 0.png, 10.png, 100.png

I tried with a format string but didn't really work. is there a way to achieve this?

my goal is to have 000000.png, 000010.png, 000100.png instead varying number of digits.
