Excel: How to create custom age-range groups in a Pivot Table?

Question

I have the following data list with two columns: 'Division' and 'Age.'

I want to put this data into a Pivot Table and group the ages into specified ranges; however, I'm having issues figuring out how to get around grouping them into set increments that don't vary. My first range would need to be 18-24, my next would be 25-29, then 30-34, 35-39, and so on until I hit 64. Then, I would have 65+ all grouped into one, like so:

The "Group" option provided in the Pivot Table selection doesn't let me customize my ranges so that my first range can include 6 values while my second only includes 5 values.

Is there a formula that could accomplish this task?

Any help you can provide would be much appreciated. Thank you.

Start your groups at 25, Excel will automatically group anything below 25 into its own <25 bucket. Then add a filter to the Labels to only include those that are greater than or equal to 18. Now your <25 bucket really represents 18-25. If you want to, you can click on that cell and rename the group "18-25", it will still count the same records.
