Vignette validity

Hi,

there’s a feature I miss in the Waze application.

When I buy a limited-validity vignette (e.g. one that’s valid for a year or 10 days), I’d like it to be applied in Waze only during the period of its validity, after which it should either be removed or I should be notified that it has expired.

It would also be useful to be able to set the start date in the future.
I hope this topic is not a duplicate.
