is there quick way for copy part of page blob to another page blob

Question

Hi All,

I have a question:

Is there a way to copy part of page blob to another page blob without downloading the data and uploading it. For example if I have two blobs, and I want to copy data from blob 'a' to blob 'b', but not the entire blob, just several pages, let's say from offset 100MB until offset 770MB.

Obviously i can download the data from blob 'a' then upload it back to blob 'b'. But I wonder if there is a way for doing this at the cloud without the need to download data to my local machine.

your reply will be appreciated.
