Automatically purge stale computers from console

Please add some functionality that allows the automated purging of systems out of the CW console based on customizable criteria such as GuestInfoUpdateTime.  Imagine a scenario where a company has 10,000 computer and all 10,000 computer were replaced.  Your CW console would then have 20,000 machines unless someone manually deletes the original 10k computers, rather than them auto purging after a certain time period or criteria is met.
