The choice to save believers is a corporate election before any individual believer had been chosen. The claim a corporate election "entails the choice of individuals" is false. Say I am driving to the store and I choose to buy grapes. Have I chosen individual grapes? No, of course not. Only when I subsequently pick a package of grapes, were the individual grapes chosen. Same thing with salvation. God chose to redeem believers, but did not pick any individuals. Why, because we existed as not a people chosen by God, before we were chosen as a people for God's possession. 1 Peter 2:9-10.
