RMAN level 0 hot backup and archive logs

We currently have a backup script that executes RMAN level 0 backups once per week and level 1 backups every other day. The code is generated dynamically via a shell script and is then executed. Here is a recent example of a level 0 backup that was executed...

    sql 'alter system checkpoint';
    backup as compressed backupset incremental level 0     format
'/opt/oracle/backup/bioocld1/sets/2016-01-02_211929_lev0/2016-01-02_211929_lev0_%s_%p'

    database;
    alter system switch logfile;
    alter database backup controlfile to
'/opt/oracle/backup/bioocld1/sets/2016-01-02_211929_lev0/2016-01-02_211929_ctl_bk';

Archive log backups are not currently included and are backed up via a separate process however I want to change this slightly. I would like the level 0 backup sets to also include the minimal set of archive logs needed to recover the backup. The reason being is that sometimes we might need to take a copy of a recent level 0 backup and archive it and we will want to be able to restore and recover at some future time when the archive logs are no longer on disk.

I guess I can query v$log to get the current archive log sequence before the backup starts and use "backup archivelog from sequence nnn" after the database backup but wondering if there is already some RMAN functionality/syntax that I can use to achieve the same?

Thanks,
Ken.
