Backup UCS script with Ansible

Hi experts,

I am writing an Ansible script to backup UCS files through API calls and hit the issue when the file is bigger than the max chunk size (1048576). I found a way to download the file in pieces using the Content-Range header, but it is still challenging to merge all the pieces as I cannot do that locally on the Ansible host and looks like Ansible does not provide the merging functionality. Anyone with an idea of doing this through Ansible?

Thanks a lot.
