Thanks for working on this @Antsalacia ! I think we can just put the tag at the end of the mosaic tif file and not every single split box. So it would only be needed here (and not where you put it for now):

Thanks for working on this @Antsalacia ! Now we need a default label in case the user doesn't pass one. Any ideas?

[Antsalacia]

We could add default ?

We could add default ?

I think the point here would be to have a different label for different areas running on the same date so that they don't get replaced. Having default would just change the file name but still overwrite.

Maybe a tag like lat{latitude}_lon{longitude} could make sense, where latitude and longitude is the center point of the bounding box.
