Option to Bind Keys to a Combination of Keys

i’d really love to see the option to bind keys to a “combination” of keys , for example something like [A]+[B] to open your collection book for example . i bring this up mainly because i much much preferred doing ctrl + z to undo, & since there’s no option to rebind undo & redo to ctrl + w/e without a third-party program it’s really been an annoyance for me

unfortunately i can’t think of anyhting off the top of my head that would be extremely beneficial from being able to bind keys to a combination aside from undo + redo but regardless i’d still love to see the option!
