Enhancing New+

### Description of the new feature / enhancement

I love using the New+ feature to create repetitive folders. My job requires me to make folders every day for the same jobs every week. The only thing that changes is the job number and the job date. Some jobs are for the same day, so the New+ feature where it will autofill the date works perfectly. For the jobs that are a day or two in advance, I'd love if there was a way to put something like MM-DD+1-YYYY and it put tomorrow's date instead of today.

### Scenario when this would be used?

When I'm creating jobs for the following day, it would speed up my workflow to not have to change the date from today's date to tomorrow's date.

### Supporting information

_No response_

Start by locating the New+ feature and reviewing how its current date autofill works. Trace where folder-name date patterns are interpreted, then define the expected behavior for dates offset by one or more days and verify that existing same-day autofill still works.
