Let users go back to an AI version before manual edits.

"When I initially created an estimate amounting to $23,000, the AI generated a version reflecting that amount. However, after making manual edits to the estimate, the system updated the current version without creating a new one. As a result, if I want to revert to the original version, only the most recent (manually edited) version is available, and there's no option to revert back to the original estimate."
