3PAR storage- How to change path policy in Vmware 4.1

I want to know can we convert the existing LUNS on vmware 4.1 environement to rounrobin

We have a 3PAR storage and we are able to convert the new LUNS with a single command but can we convert the exixsting LUNs together presented to the Host.

This is how we convert one by one which is a tedious job

List all the 3PAR devices present on the Host

# esxcli nmp device list | grep -i naa.50002ac | grep -v Device
naa.50002ac0005800ac
naa.50002ac003b800ac
naa.50002ac0039300ac

Change the I/O path policy to round robin for each device identified in the previous output
# esxcli nmp device setpolicy --device naa.50002ac0005800ac --psp VMW_PSP_RR


Is there any command where I can change the path polict to roundbin at once together presented to a particluar host.
