List all monitored machine names on which an employee has been monitored, including the first and last dates seen on those machines.
Idea 1: On an employee's page, in a column under EDIT INFO and ACTIVE POLICIES, list the various machine names from which the agent has reported. Include the machine names even if the computers have been deleted.
Idea 2: The same general idea as #1 but perhaps there's a way to have it appear on the overarching List of Employees. It could bridge the gap between the existing List of Employees columns First Online Time/From and Last Login Time/From in cases where there have been several+ machines used. This approach may necessitate a change in how deleted machines appear in name on the List of Employees.
In the meantime, there is a workaround to see all of an employee's historical machines by configuring a custom BI Grid Widget and using a sufficiently long date range.
