rclone copy . gdrive: works 
I've added rclone to the right-click menu, but would also like to pass flags. Is that possible?
I've tried:
C:\Windows\SysWOW64\cmd.exe /K "H:\rclone\rclone.exe" --buffer-size 512M --drive-chunk-size 512M --checkers 8 --transfers 8 --tpslimit 8 --max-transfer 750G --fast-list --exclude-from excludes.txt -P
... but the flags are not being passed.
Any way to run rclone with that exact set of flags each time, instead of needing to type them all out?
