Microsoft Azure Blob storage update

Question

Is there any way to update an Azura Blob Storage by scripts?

I can write a PowerShell script that deletes the actual content of a Blob storage and then upload the content again (obviously, with the changes I made in the meantime), but to avoid this tedious and data-consuming process, is there any better solution to compare the content uploaded and only upload files which are changed? I have seen some solutions in C# but I'd like to use PS script. Thanks for the recommendations.

Edit after comments :

Think you could be after Append Blobs:

I believe it can only be applied to a specific storage blob type
