DROP Partition of non owned schema

Hi,

I have 2 schema s.

Schema A has a table named T1 and has partitions PART012015, PART022015, PART032015

Schema B need privilege to drop A.T1 partitions.

Without giving DROP ANY TABLE privilege is there any privilege where I can give targeting only specific table. A.T1.

According to the security standard providing DROP ANY TABLE to user B will gain the schema B to drop any tables in all schema, how can I avoid this.
