ssh compression on command line without creating profile?

I am using the command line to transfer large files:
winscp3 account:password@server /command cd ... put ... exit

is it possible to activate compression for this without first creating a profile for the server?
(i can set "enable compression" in profiles, but i don't know how to activate compression as default for new connections or on command line initiated connections)

The only way is to preconfigure a profile or to make it default using Set defaults button on login dialog.
