Further development of album feature

I am working on a large score, a Latin mass for symphonic orchestra. Editing the entire Mass in a single MuseScore file does not work today. The performance gets already bad with some bigger parts. So I put every movement (Kyrie, Gloria, etc.) in a single file. But a lot of work must be done several times, e.g. all the formatting configuration needs to be copied to all files.

Today there is the Album Feature to combine several files for certain functions. In my opinion, however, this does not meet all the "necessary" requirements for such a large score. I would therefore like to encourage the further development of the album feature. I would like to see the following functions:
1) I open the entire score from a single file (maybe a new file type). The individual movements defined by the user should be saved as separate files.
2) The main file defines all properties that apply to the entire score: Title, composer, instruments, copyright, etc. fonts, spacing, sizes, page format, etc.
3) The subfiles (a subset of the current file format) no longer contain the above properties, only the notes, etc.
4) To optimize the display performance, I suggest that the entire score is not displayed in the application at once. The movements could be shown in additional tabs, as is already done with the "parts" today. (From my point of view 2 levels of tabs would not be a problem. Or maybe there is a much better display format.)
5) All actions that refer to a single MuseScore file today should refer to the complete score (the new album), including, for example, the "parts" that also could optionally be saved in separate files.
6) I think it would be important to develop this feature in consideration of collaboration functions. Large works are certainly more likely to be developed in a team than by one person alone. The basic requirement would be a mergeable file format, i.e. XML rather than a binary format.

Lets take this as my initial post. I am willing to work constructively on this idea and, if necessary, on its implementation. Now I am looking forward to your opinions and of course also your assessment regarding the probability that such a thing would be implemented at all and in the foreseeable future.
