How can I set second data to nested tables?

I have 2 nested tables and would like to add a data to these tables on script. However I couldn’t do that.
(Parent table - Header, nested table - item and Sub)

First of all, I created parent table and 2 nested tables in advance.

Second of all, fist script over wrote existing records. (see Set fist data step)

Finally, next step is going to add a new data but I only could either item table or Sub table. (see Add second data step)

How can I add the data to both item table and Sub table on script?
