Pluggable database duplication

I know that I can unplug the pluggable database and plug it back into the same CDB or another CDB, but I cannot duplicate it:

    [oracle_at_rac1 ~]$ rman target sys/qwerty_at_ora12c-1:1521/     auxiliary /

    RMAN> duplicate target database to orcl pluggable database rcat from     active database;

    Starting Duplicate Db at 18-FEB-16

    RMAN-05501: aborting duplication of target database     RMAN-07536: command not allowed when connected to a Pluggable Database

The difference between unplugging and plugging back into another CDB and duplicating is drastic. Duplication can be done without downtime, while unplugging cannot. The first step of unplugging the database reads: Do "alter pluggable database <pdb name> close immediate; That is downtime. Are there any plans to allow "duplicate database", while connected to a pluggable database? Regards
