Model the uninterruptible power supply (UPS) and what they are powering

I think it would be useful to model the fact a computer or network equipment (and maybe other asset types) is powered by a given UPS (helps for power outages).

I'm not asking to create new assets types for UPS (I am using peripheral for that) but being able to link a single peripheral to multiple computer (which is not possible at the moment, it can only be linked to one computer) and/or to multiple network equipments (it's currently not possible to link peripherals to anything other than a computer).
