No first hand knowledge on the V2500, but it is common on other engine/aircraft - the engines are common, just pushed a little harder at the higher thrust rating (commonly referred to as 'turning up the wick').
It doesn't even take different FADEC software - the software usually contains all the certified ratings, there is a "rating plug" that plugs into the FADEC that tells it which thrust rating to use. It's a relatively simple task to change the engine rating - new rating plug and nameplate - via an engine company service bulletin.
