Sure.

At your shell prompt, type:
man 5 crontab

You'll find the man page for the crontab file, which includes multiple
examples of cron entries.  All of those use the time specification,
though, rather than the @reboot keyword.

An example using @reboot:
@reboot			/usr/local/bin/screen -d -m Rtorrent

You can edit the crontab for the user with this command at your shell
prompt:
crontab -u username -e

This will dump you into your editor, editing the crontab file for the
user "username".  Type in the crontab entry (for example, the one I
used as an example above), save, and try restarting the jail.
