Feature Request: Scan for unused computers and mobile devices

[sdpalmer]

For computers, usage would be determined by management status being unmanaged or Last Inventory older than x days or Last Check-in older than y days, or any combination of the three, where x and y are determined by fields to enter the number of days for each.

For mobile devices it would basically be the same thing with the exception of Last Check-in since that does not exist for mobile devices.
