Album function

MS2 had this album function which I found extremely useful in preparing large scores. It allowed splitting the piece in manageable pieces and assemble them into one score at the end. Unfortunately the function was dropped for MS3. Upon my question I was vaguely promised that MS4 would feature a similar function that would help me with my problem. This seems to have been abandoned. I wonder if it is still on the list of things that might be offered at some point.

I have workarounds for this but a straightforward way to simply combine two scores into one would still save quite a bit of time.
