Ability to have alternative descriptions for lineitems

When creating an application it is often necessary to have a "technical name" for a line item that the model builder understands but may mean less to an end user or that means different things in different locations or where you want to translate the lineitem into a different language. I would like the ability to store different descriptions for lineitems that can be toggled on and off either by the user or by the model builder or be based on the locale of the Browser settings.
