For example i want my Perfect Sword: Unbreaking 3 sweeping 3 sharpness 4 looting 3 knockback 3 fire aspect 2

I put the enchants in, see that its currently impossible or some absurdly high number above 8000, go try for something else, and then want to check again if the sword is realistically possible now. Now i have to put all 6 enchants in again, and if its not realistic, i have to repeat the whole thing. this is why i think saving and loading things to scan for would be useful.
