Static data that need to be updated monthly

Hello guys, I got an issue that needed a solution from you genius guys. I am passing dynamic contents such as blog post to gatsby frontend from contentful CMS. Now i needed some static (not dynamic like blog post) data placement that might update later, more like monthly. Static data i mean:

  • to-do: 10
  • doing: 3
  • done: 1

When i done some to-do i must update done and doing, to-do accordingly. So is there any solution can you guys provide? Because using content-model for this is kind of a dull way i perceive
