Change Scrum Template

In Monday Dev, we do have a standard template, my client want some adjustments to the Scrum template. However, I do not see the possibility to change the template (the template is from Monday itself). I can change every single Scrum team board but that seems not feasible, having 15 scrum teams and more are coming.

I hope some one can help me on my way. :slight_smile:

Thank you in advance!
