Ability to turn a signed proposal/document or even an "estimate" that have been approved into a "job" with a status of "waiting to be scheduled" or "need to be schedule" and have the estimate or proposal "linked" to the "job" and vice versa. Then allowing the "Job" to be "scheduled" on the calendar and the status changes to "scheduled" on the Job and estimate/proposal. Same with the status of "completed" once the work is completed.
