Have LM use a more immutable resource index for networking devices such as serial number vs IP address

I was notified by LM TAC that LM uses the IP address as a device index to know if it has already monitored a device when discovering new IP's. Unfortunately this makes many mistakes when devices are using DHCP such as AP's, or the Controller ports of SD-WAN appliances. I know several tools that use a more immutable attribute such as the device serial which is found in the ISO OID tree vs the product specific trees.  Using this attribute would allow LM to easily detect changes in IP's for devices it is already monitoring. It would also be aware when a device is replaced by referencing the serial with the hostname and finding a change, making the product a bit more intelligent in larger networks where changes happen more frequently.
