Job Number

Is it possible to have an automated Job number created when a Job is started? We often have reshoots that would pertain to the same property over time either as a re-shoot or a just a new listing down the road. This helps us with accounting, but can also be extremely useful as a search option in the search bar. As for accounting, this is often useful when we have a batch invoice with a large amount of jobs listed on there. it would be good to have that visual on the jobs screen and invoices.
