Is there a formula I can use that would show the last date that a specific column was updated? For instance, when someone checks the checkbox column, could I have a formula in another column that would reflect the date the checkbox was checked? It wouldn't work to have a formula that showed when the entire row was last modified as we add notes to a row even after the checkbox has been checked. However, if there is a formula I could use to show me the date a specific column or cell was last updated (not row), that would be great. Thanks!
