[FEATURE REQUEST] Extra Item Options for Randomizer Mode

Hi I would really like to see like 3 extra options in the item catagory one for starting with Broken Giants Knife and the other two for starting with the Giants Knife and the Biggoron's Sword. But i mainly just want to be able to start with the Broken Giant's Knife because thats my preferred way to play as Adult Link.

Also preferably I'd like a sub option for starting with the Broken Giant's Knife or the Giant's Knife that would remove finding the Biggoron's Sword from logic so i dont have to worry about it being upgraded by accident.

I'd code it myself but i have no idea where to look for the code and how the randomizer works. I dont have much C or C++ knowledge either so I'm kinda useless on that front for anything more than ideas.
