welcome to the forum,
seems very niche, but rclone is open-source, you can write the source code yourself or sponsor
there are many things i wish rclone did, like create microsoft VSS snapshots, so i shared a script in a howto guide and wiki
How to enable VSS for rclone on Windows
or create s3 temporary session tokens, so i wrote a python script for that.
the docs are open source, anybody can edit them.
tho, inserting that linux only script into the docs is not good idea for a bunch of reasons.
