We just replaced 400 computers, with AiO, so there is no separate monitor attached and the monitors are being sold. I would love an option that if the asset that the monitor is attached to is not active, that the monitor is marked not active too.
Or something along that lines, as I am sure it's not that simple.
Added to the wish list. You could write a script to do this and execute it under Configuration\Database Scripts. We do not currently provide support for writing custom database scripts however and recommend performing a database backup prior to running any scripts.
