How would I go about resetting a single players data?

Basically, during the testing of a game, I messed up my inventory which causes my inventory to stop working how it should. One fix we found, was by resetting the data store for everyone. But due the amount of save data, we reverted back so everyone kept their items. How would I go about only changing one persons data store so it loads clear and saves as a different loader. - What I mean by that is, all the other players save and load how they normally are, but the other player (me) saves and loads with a different store to allow my inventory to work again?
