Create an object having attribute values from different objects in a list

Hi, I am using Bootstrap multiselect widget. It expects an entity having all the multiselect values. But I have a list of objects. And I want specific attribute value from these lists of objects consolidated in an entity. So that I can use the newly created object in my widget. Is it possible?

It seems not possible. 

Did you tried, a new entity which has the values stored from your list of objects. 

Documentation says, it supports, Microflow as a datasource, meaning you can manipulate the data using microflow the way it is needed. 

I did not tried this widget fully, yet.
