Feature Request: Multiple movements in one score

I'd like to be able to have multiple movements in one score. Each movement functions like an independent score, but all movements are grouped together in one 'master' score. Each movement can have its own title and subtitle, and headers/footers can be different for each movement (ex. header/footer option of 'movementTitle' or 'movementNumber'). Movements can be exported individually, but the master score can also be exported. (Likewise for parts, in both each movement and the master score.) The export of, say, Violin I from the master score would result in a homogenous document that flows between movements. (Thus, for example, if the end of movement A has 2 staves at the top of the page, movement B can start on the same page, below the end of movement A.)
