help with fast travel

so.... i did a little naughty thing, i may or may not have given my self a unholy amount or hearts and in the temple of time i was able to open the door first try. so the event to get the final shrine never happened to me thus i never got fast travel. is there a variable i can edit in my save file to enable it (master editor from https://www.marcrobledo.com/savegame-editors/zelda-totk/) so that i can enable it? i dunno what the variable is called and i cant start the event anymore because the door is already open.

if you have any ideas please lmk, i already beat totk before so now im just tryna do it on easy mode
