initial value

How to set the Select widget Initial value from BDM object

I want to use business data to set the initial value of Select widget.

I will explain what I would like to achieve.
In the previous task, I get the value of the Select from user and set this data in business data object, and then use this value for the Select widget's initial value in the next task, so the user does not have to select, but still be able to change the value of select if it is necessary (the actor groups in this 2 tasks are different, so this 2 user should be different person).
