Duplicate Computer names under different asset states

We are running into an issue with ServiceDesk with swapping out computer hardware. An example is that we have an old computer (COMP-A). This computer is currently in ServiceDesk as an asset. We are replacing COMP-A with new hardware. The old hardware is to be discarded. Even though I switch the asset state to disposed on the old COMP-A computer, I cannot add the new COMP-A computer into ServiceDesk because it detects it as a duplicate.

How can I get ServiceDesk to allow for the tracking of disposed computers, as well as the new ones with the same names?

Some ideas that I haven't tried yet:
1. Can I move the retired workstation to a non-it asset group to have it exist with the IT asset with the same name?
2. Can I rename the retired workstation to a different name, and have it exist with the new COMP-A workstation?

If there is no functionality to track disposed assets within ServiceDesk, are you planning on this soon? One of the main reasons that we wanted a good asset management solution was to track the full lifecycle of a pc automatically. It seems like ServiceDesk should easily have this ability.

Thanks for your help.
