A Barracks with the same flags is a Barracks no matter what the Building Name and a Barracks allows Veteran Units and Upgrades.
Due to programing, I am not sure there is any adjustment that will allow what you are wanting to do.
If you flag and use your various Buildings to upgrade Units those Buildings will also allow all units to be built as Veterans because each of those Buildings would in reality be a Barracks.
