Please find this community post on how to import “Story points” dimension as interval dimension:
Then you can define intervals for your report to group story point dimension members by custom itervals.
Or you could create calculated members in your current “Story points” dimension using this formula:
Aggregate(
Filter(
[Story Points].[Story Points].Members,
CatchException(CDbl([Story Points].CurrentMember.Name)) < 40
AND
CatchException(CDbl([Story Points].CurrentMember.Name)) >= 20
))
This example above would filter story points between 20 and 40
