If you're willing to go through that much effort instead of scrolling through the day view and month view then you could easily just open up mission chief, look up what people have contributed and type it into the spreadsheet?
I don't think MC is at the stage where it will support excel etc and personally I don't think it's needed.
I already go through it daily and record manually what each player contributed. What I'm asking for isn't something massively complicated.
THAT is dedication for you!
If we can't have missions spawning properly yet, it's definitely not something that would be worth looking into in my opinion for the DEVs, as I don't believe that many people would look this deep into the figures to work stuff out about their alliance.
I enjoy working out figures and various statistics I'm actually trying to develop a full set of spreadsheets for the game so I can see each stations setup and how much it cost as well as bringing together the information to display statistics for my set up.
I keep a log every Thursday (don't ask why that day) of user earnings in our alliance to see whether or not a player is active. It also gives an indication into our busiest or quietest weeks. For an alliance with only a few dozen members, it's not very difficult to manage.
This is basically why I'm doing it to see what we earn and when we earn most and get an average daily income.
