Implementation of nested decision table

Hi All,

I have a requirement where o/p of 1 decision table needs to be used as 1 of the i/p of another decision table. For this i want to call the child decision table as 1 of the i/p condition in parent decision table. But in Rule Development perspective (in Designer) i cannot see any option to include another decision table.

We are using SAG Suite V8.2. Please help.
