Create a Task Repeat method where after completion the next task would become due with auto-incrementing or decrementing values.

Examples -
A "Basic Training - Week 1 Day 1" task when completed would create a "Basic Training - Week 1 Day 2" task

Annual events like Birthdays & Anniversaries would be able to be labeled with a numeric progressing occurrence number.

A weekly repeating "Week 8 timesheet due" on Feb 27 would create a "Week 9 timesheet due" for March 6.
