Archivelog - 2nd copy on local disk

Hello

We have a 2 node RAC on Standard Edition 10.2.0.4 on Linux
Archive log desintation is +FRA

+FRA is on SAN

Is it possible for us to set a second archive log destination to LOCAL file system
for both the database instance so that even if we loose +FRA we will have a local
copy of archive log from both instances that we will be able to use for recovery

Here is how it is currently set up

log_archive_dest_1                   string      LOCATION=+ARCLOG/
log_archive_duplex_dest              string
log_archive_format                   string      LOG_%t_%s_%r.ARC
log_archive_local_first              boolean     TRUE
