Using the field "Debit address from" you can specify that a lease's debit address should be retrieved from the tenant you have set for it.

 

For more information on how to set a debit address for a lease, see the section "Set a tenant for a lease". Then continue reading in the sub section "Set a debit address for a lease". Note that the section "Set a tenant for a lease" is a sub section to section 8.1.4.
