Not every province, only those that get changed by occupation or other events. Outer Manchuria changes into Prymore when Russia spheres Manchuria and selects its decision. If China reconquers the province from Russia it remains as Prymore rather than return to Outer Manchuria. That makes no sense whatsoever and should change. Alsace Lorraine is the same case, but because both nations are European: France and Germany, than Paradox added a decision for France to revert the province from the German name back to the French name. Will Steel, and I agree with him, simply want this option for all provinces that get their name changed if the original owner(at the game's start that is) reconquers those provinces since they still have cores on them.
