Is it possible to use variables in a NCF file? What about one for a date?

Basically, I got a NCF file going that will shutdown my MySQL server,
copy the database folder to another location, then start back up MySQL.
Which will work. But I'd like to go one step further by using a variable
date to the destination folder. For example, I'd like to copy the
database folder to database.%today's date. That way, I'll have a history
of files.

Is that possible with NCF's?

Thanks in advance.
