On any job that includes a schedule option ... allow for a selection that would do a one-time only execution of the job.

For example I have a use case where I want to schedule a transfer job for my migration from on-premise to the cloud to happen overnight ... I'm not always available to manually kick off overnight jobs and putting them on a "fake" schedule is a less than ideal solution (I don't want to run the risk of duplicating data if I forget to disable the schedule in time). I have 8 years of data to move in a version controlled cabinet, so I need to do it in 1 year chunks and overnight due to the volume of data.
