WinRM Python File copier plugin : only appends, never overwrites?

I am unable to change the behavior of the WinRM File Copier in Rundeck, it is a Python based plugin, launched from a RHEL 7.9 (Maipo) Linux Rundeck server that is connected to an Active Directory server.

When it copies an existing file from a Rundeck server (Linux, with Kerberos/Active Directory authentication) to Windows based targets, it appends its content. I am looking how to force overwriting of the target file instead. Until now, I have to delete the target file each time before a file is copied to the target.

Does someone know how to modify this behavior in order to overwrite the content, not append it ? I checked in several Rundeck settings without success.

Rundeck version : 3.2.1-20200113 WinRM Python File Copier plugin: 2.0.12 WinRM Node Executor Python plugin: 2.0.12

Python2 is the version used on the Linux RHEL 7.9 Rundeck server

Thanks
