There should be a way to overwrite a calculated property with a manual input. There are cases where we want to automate a value 9% of the time, but edge cases that require a rep to manually overwrite it. For example, when creating a custom calculated field for a contract date like subscription end date, or renewal date. We may want to automate those in most cases, but we still want a rep or leader to be able to make an adjustment if there is an edge case that falls outside of the automatic calculation.
