Filter by number range in Pivot Table Filter Area Field

[alag76]

I have a pivot table which counts the number of records per category. I would like to filter it so it only counts records that are older than 100 days. I added a filter to the pivot table area for the age of the record but to filter I have to check each box for any value over 100 and that is time consuming and cumbersome. Is there a way to filter for a range of numbers in the filter area field or other suggestions on how to do this in a pivot table? Thank you!
