Show which bucket has multiple values in statusmap

I have the need to display statuses that can overlap on each other time-wise.

Does status map have an configuration to determine which bucket has multiple values, like darker shade of color, so that it’s easier to tell that there are multiple values there and I don’t have to hover over a bucket to see if there are other values.

I’m thinking of setting smaller time range for each bucket (e.g.: one bucket shows from 01:00 - 01:05) - but not sure how to change it and if it will do.
