Overwrite the original file when performing transformation

[seidme]

I'm trying to overwrite the old file when doing some transformation as I don't need to keep the version before its being transformed (e.g. resized). Something like the following:
https://cdn.filestackcontent.com/resize=width:300/[handle]&overwrite=true

I can't find anything in the docs, only this about overwriting?: https://www.filestack.com/docs/api/file/#overwrite

Please advise, thanks ^^
