Add a third column in the Property Sheets

I have a property sheet where I list the name and the value, but I would like a column inbetween with information about the name or value.

In the games we work on, we have features of the ship as names, like Primary, Secondary, and so on. We also need to track the armor on those as well so I use Primary (heavy armor) or Secondary (light armor). Now that becomes a part of the name of the property and I would like to move that modifier to a separate column that accepts text labels at least. Sort of like BEM naming in CSS. The name and then modifier then value.
