append to file

[PhMota]

I need to append to a remote file. So that I don't need to download, append and then upload the whole file. Since there is the functionality of uploading the files in chunks, I imagine there must be a way to append to the remote file by sending only the new data. I tried to understand the logic behind the chunk upload inside of a upload_session and it seems possible.

Given this, is it possible to implement an append functionality? Or at least help me do it

Thank you in advance
