Custom Inventory Field

I have been tasked to create a custom inventory field in Zen 11.2.3. I am not sure if this is possible. If not, is it possible to modify the name of a field to a different chosen name?
We have some software running on certain computers that do not show up in the inventory in Zenworks. It is because it's a module contained in other software that is inventoried. Hence the need to create a new field

Any help would be appreciated
