Selection widget would show up in the component before the whole component executed.

I have this workflow here which I want the users to have some selection options in the columns and single selection widgets before executing on the rest of the workflow. However, with this setup, when the user click on the view (magnifying glass) icon on the component, it is executing through the whole component with the default values before the setting would show up (or not show up because the default setting is incompatible with the data input). How should I do this such that they can pick the selections BEFORE the rest of the workflow is executed?
