Select Registry as Column or ask for ModelName

I made a registry key, which ask for the real modelname, like ThinkCentre M73, Manufacturer is LENOVO.

I would like to ask, if there is a chance that this regkey can be choosen as a column in Allcomputers section. Here:

It is important for us, because the OCS gather only an SMODEL (maybe from BIOS section in registry) but it is say nothing for us, we would like to know the best-known model name.

Or if it is not resolvable, is there a way to change what to inventory from the client? Is there a file where I can change it?

Thanks for your help!
