Configurable List: Ability to set up default values on widget fields.

Check Preference Number table 

There is 3 row. First column is PREFERENCE.

I need default value in Preference No. 1, 2, 3 respectively. 

like this:

Preference No

1

2

3

This is not currently possible, but I will open a feature request on our second level, although we cannot provide an ETA or ensure this will be implemented, we will let you know as soon as we get any update about it.
