My suggestion was not seeking any new data, just recording what you already have but in a slightly different way. The only 'difference' is that I'm suggesting an entry like the word 'January' is entered on the base data sheet as a January date number proper, say 1/1/2021

How is the data populated on the Base Data sheet? I can't see any connections or links which implies it's being manually added. If that's the case and since no new data is different it could presumably be added as I described.

Perhaps it would help if you uploaded the ms form that the engineers use with an indication of how it moves from the phone to the Base Data.
