Asset location flexfield for new international book

Hello Community.  We are rolling out Oracle to our international entities and want to use Oracle Assets in the new ledgers.  We have only had one asset book for the US since going live on Oracle and the location flexfield is set to State, County, and City.  However, we will need to populate Country, Province, and City for our international entities.  I understand that Oracle Assets is implemented per instance and not by Operating Unit and that no changes should be made to the location flexfield once setup and used, so is there anyway to have a different location flexfield
