From the management console, you can choose one or more tables not enabled for multi-tenancy, and enable them. You can then make decisions about partition allocation for any of the table's fields and indexes that have not yet been allocated.
Note that when you enable a table for multi-tenancy, you are affecting all tenants for a selected database.
