Azure upload block size adjustment

I would like to make a feature request for uploading to Azure Blob storage, where we could adjust the upload block size to something different than the default 4 MB. This small block size leads to a great number of WRITE operations, which affects cost. Azure Storage Explorer has a setting for "upload in the fewest blocks possible" which sets the block size to 256 MB, but the limit in the API is actually 4 GB. I have uploaded in 1 GB chunks in the past with zero issues. The ability to adjust this ourselves would be very helpful. Thank you!
