There’s not been any further progress on this yet, I’m afraid. We’re working hard on improving Breww all the time, but with the requests coming in as quickly as they do, it can be hard to keep up with! We will always post an update on the thread if it’s been completed.
You can upload files to batches in Breww, and they get stored safely in a list of files for record keeping, rather than being linked into your brew sheet as such. An upload cannot change the data stored in Breww’s brew sheet, but you can keep a copy of a spreadsheet brew sheet against the batch, if that’s what you’re looking for?
You can also manually create custom calculations in Breww already and show these on your brew sheet, and these can use readings entered into the brew sheet earlier, but they just cannot use information linked to specific batches of ingredients yet (other than alpha acids calcs). For more on this, please see the “Calculated fields” section at 📘 Introduction to production
