Can i start Impossible Mode from sratch?

[Hwoarang_21]

Im playing Hardcore and i dont like that i have tons of weapon parts since the beginning and a lot of resources, im not gonna use the parts to make them more challenging but still, i remember Dead Space 2 HARCORE run was brutally amazing and you need to be extra careful and in that one you dont have tons of equipment to your disposal because they stack up from previous runs.

When i finished the platinum i need something real challenging so is there a way to  start Dead Space 3 Imposible from scratch???

Because is not unlocked in a new save.
