By default, Roastmaster will create a new bean lot every time you ADD inventory. Unless you “cancel” the new bean lot, or turn the feature off in preferences, you’ll have a record of every time you add inventory. You can see those by tapping the “Bean Lots” cell of the Bean details view.
But your question is about roasting…No, there’s no way to see the individual debit entries that Roastmaster makes to your inventory, simply because it’s designed to be automatic. I’m not against adding something like that - just never saw the need.
Whenever you add a roasted item in the roast console or edit its weight, RM will debit the “weight” amount from the applicable beans’ inventory automatically. If you change that weight later, switch the roasted item to a different item, or delete the roasted item from that roast altogether, then the amount is credited back to the original bean(s), and then debited from the new item if applicable. In short - it tracks the changes as you go.
So, unless I’m misunderstanding your question, you shouldn’t have to keep track of that yourself. If you configured the roast, and it has a bean or blend tagged with a weight, then that would essentially serve as the record - you’d know that it has already been debited from your inventory automatically.
Let me know if I’m misunderstanding.
