Parameter Placeholder in Editor.

Hi I’m in need for help or direction with this one.

What I want to do is to instantiate objects in blueprint from the construction script, that has parameters that I can manipulate.
I want these objects to act as a placeholder or dummy objects with editable parameters that later drives other things in the script.

A good example is like having the construction script create a set of dummy objects in different locations, each with same sets of parameters (different values) and these parameters would be like set temperature, wind speed, enemy density or whatever I predefined. These dummy objects should be hidden in game, only a editor tool.
