Play Rhythm in Lead

[RoR]

Hi,

I am a beginner guitarist and this is my first time post (been lurking for a while, lol). I often get frustrated playing songs that are far too hard for me. I know the game has the dynamic difficulties but to be honest i'm not a fan as i find when it raises in diffficulty my hand and finger positions are all wrong so i usually just put on 100 difficulty and riff repeat at slow speeds.

Recently i have decided to give my learning some structure and done abit of research on some songs that are great for beginner players so once i have mastered them and their associated chords i can progress to harder songs with more chords ect.

One thing i noticed is some of the really easy songs are only available in rhythm and i selected lead as my path so playing it is unavailable unless i switch.

Would there be a simple way of creating a copy of the rhythm to lead track since there is not one already, and how hard would this be to do and how?

Thanks,

RoR
