Title: Weekly time-based shipping discount (e.g. free shipping after first order each week)

Description:

I’d like to request support for time-based recurring shipping discounts.

Use case:

For example:

A customer pays for shipping on their first order of the week

All subsequent orders during the same week have free shipping

The shipping discount expires at the end of the week

The rule automatically resets every week

This would allow us to:

Encourage repeat purchases within a short time window

Reward loyal or high-frequency customers

Run predictable, recurring shipping promotions without manual setup

Question:

Is this kind of weekly, auto-resetting shipping discount logic supported today, or is it something that could be added?
