The consecutive constraints in the model currently operate with the day granularity only. That means, if we have the following shifts assigned to an employee:

This produces 2 daily sequences [Day 1], [Day 3, Day 4], because we look at shift's start times.

Some use cases treat sequences differently. There is a scope (for example 36 hours). If the shifts are not separated by more than the 36-hour limit, they are treated as a single sequence.

In the example above, the shifts would be consecutive, since "Day 1" and "Day 3" shifts are separated by 28 hours.

This is a request to introduce the new scope concept to the "consecutive shifts worked" rules, so that we can express rules like "Maximum 7 consecutive shifts in a sequence".

Moreover, the constraint ideally supports "filtering" case too, such as "Maximum 7 consecutive shifts in a sequence containing one or more night shifts".
