New Feature Idea: Countdown Timers for Official Documents & License Renewals

Dear Resubs Team,
I have another exciting feature suggestion that I believe would add massive value to Resubs: Adding a Countdown/Days-Remaining Tracker for Official Documents and Licenses.
It would be incredibly helpful if users could use the app to track the expiration dates of non-digital items, such as:
Official IDs and Passports
Driver’s Licenses and Vehicle Registrations
Certificates, Subscriptions, or Insurances
Instead of just showing a renewal date, having a "Days Remaining" countdown (e.g., "45 days left") and sending urgent alerts before the deadline would save users from late renewal fees and penalties.
Since Resubs already has a great notification system for digital renewals, expanding it to official document deadlines feels like a natural and powerful next step.
Thank you for your time and continuous improvements!
Best regards,
