Currently the only way I am aware of to do this, is to restore a single PDB to an auxiliary database and then plug / unplug to another destination.

Here is some sample syntax that will work for your backup:

export NLS_DATE_FORMAT='DD-MON-YY HH24:MI:SS' rman target /
run {

    allocate channel dupe1 device type disk format '[backup location]/%d_bs%s_piece%p_%T_%U.bkp' maxopenfiles=2;
    allocate channel dupe2 device type disk format '[backup location]/%d_bs%s_piece%p_%T_%U.bkp' maxopenfiles=2;
    allocate channel dupe3 device type disk format '[backup location]/%d_bs%s_piece%p_%T_%U.bkp' maxopenfiles=2;
    allocate channel dupe4 device type disk format '[backup location]/%d_bs%s_piece%p_%T_%U.bkp' maxopenfiles=2;
    allocate channel dupe5 device type disk format '[backup location]/%d_bs%s_piece%p_%T_%U.bkp' maxopenfiles=2;
    allocate channel dupe6 device type disk format '[backup location]/%d_bs%s_piece%p_%T_%U.bkp' maxopenfiles=2;
    backup as compressed backupset filesperset 4 keep until time 'sysdate+1'     tag ‘pdb_bkup' (database ROOT) (pluggable database 'pdb$seed','[pluggable name]'); }

For the restore (you can use existing full backup if you have it.:

export NLS_DATE_FORMAT='DD-MON-YY HH24:MI:SS' rman auxiliary / | tee /db_share/rman_migration/[container name]/rman_auxiliary/restore_auxiliary.log startup clone nomount pfile='/db_share/rman_migration/[container name]/rman_auxiliary/auxcdb_pfile.ora'; set decryption identified by '[tde password if necessary]'; run {

    allocate auxiliary channel dupe1 type disk;
    allocate auxiliary channel dupe2 type disk;
    allocate auxiliary channel dupe3 type disk;
    allocate auxiliary channel dupe4 type disk;
    allocate auxiliary channel dupe5 type disk;
    allocate auxiliary channel dupe6 type disk;
    duplicate database to auxcdb
    pluggable database [pluggable name], root backup location '/db_share/rman_migration/[container name]/rman_source'     PFILE /db_share/rman_migration/[container name]/rman_auxiliary/auxcdb_pfile.ora; }
