I've updated the spreadsheet to fix the bugs identified in the container selection logic.
I've also added coopertition bonus selections.
I haven't added a reset feature as the only way I know how to do it is with macros, and there's apparently no way to save out a VBA macro from within LibreOffice, so it's not going to work for excel users (pretty much everyone - i know). If you know of an alternate way of resetting the fields let me know.
If you want to add that feature yourself, its as easy as recording a new macro. Typing in defaults in every yellow field. Stop macro recording.
Then
link the macro to a button. I'd do this but don't have access to excel at the moment.
