Having Custom X-Tone (Equal) Temperament Tunings

Recently I've been getting more into different forms of tuning that the usual 12-Tone system that's used in most Western music, and I was thinking that a feature that allowed users to make their own tunings (either individual cent values for each note or a way for Musescore to automatically make something in a specific Equal Temperament system) would be very useful, especially for those wanting to expand their musical vocabulary and/or wanting to branch out into other forms of music (such as maqam and other mid-eastern music).
