Managing Event Payment Amounts for Accurate Data Analysis

Hi everyone, I have a question. I want to create an event called “Payment” with three properties: amount and type_action, which includes (add payment, delete payment, edit payment). This event will be triggered from the backend when the user adds, deletes, or edits a payment. My problem is with the amount property. For example, if a user adds 7K, then edits it to 4K, and I want to analyze the data using a line chart to see the total amount, how can I make sure I’m only summing the final (correct) amount? In this case, I want the total to be 4K, not 7K + 4K = 11K.
