Backup logs/settings to date based folder via CLI command?

Hello!

Previously you could use the "%DateISO%" command for uploading logs to a folder based on the current date.

This no longer works in 5.4

Is there any way to achieve this?

String "execute backup logs-only FW-01 ftp 10.10.10.10 User Pass /Logs/%DateISO%/"

That would result in the logs comming to the ftp server and the folder /Logs/20160614/

Same thing with the backup settings command. Anyone knows?
