Upload file if larger

I’m using rclone with video files from my PVR. Sometimes I’ll have partially extracted video files from the PVR and later on will have the complete file. Is it possible to overwrite files if the source file is larger than the destination (don’t overwrite if source size is smaller)?

There isn’t a flag for that at the moment.

However rclone will normally do the right thing I think, won’t it?
