[Observium] More IP on same device

Hi,

we use Observium to monitor even some firewalls from the outside, to check the connectivity status; does it exist any way to override the "Already got device" error when the SNMP is already within the database, just for some devices?

Just as a hint, a way to use more IPs to gain the same device, and relative availability graph only, would be great.
