The standard aging definition in our group of companies is more than 6 aging buckets. The workaround is to have multiple aging definitions that have the additional definitions and they are combined later. Ideally all this extra work would not be necessary.

Example with 8 buckets:
Not overdue (Current)
>=31 days to 60 days
>=61 days to 90 days
>=91 days to 120 days
>=121 days to 150 days
>=151 days to 1 year
>1 year
