Our eyes easily skip over the dots representing the "Days in column" on our Jira board. See grey dots below.

I'm looking for something more obvious, like how a column turns red when it's exceeded the maximum number of stories. See red BLOCKED column below.

As we are looking to progress faster on our stories, is there a way to make stories that have spent a long time in columns more obvious?
We are unable to use any add-ons due to being a large, IT-managed organization. I am looking for a solution that exists within the base Jira Software product.
Thanks!
