Adding targetline to zendesk analytics graphs

Hei there,

Here is a graph for reference.

I was wondering how to add a target ​​​​​/goal line at set levels. For example, I could set two lines at 10 and 35.

Is there really not an option to achieve it?

The best suggestion I saw is to third party integration…  let’s not even discuss about that.

Thanks for your inputs!
