[BE2012] How to change path of disk storage

Hello,

The IP of my NAS I'm using as "Backup to Disk" destination changed and I would simply like to change the path of the destination pointing to that new IP:

BUT within the properties of that Storage in Backup Exec 2012 I can't adapt the IP as the "Path" seems to be read only.

Is there any possibility to change this?? I assumed that should be very simply but it doesn't seem to be...

Thanks in advance,
 SG
