Can I use Construction Script to assign valeu in Structure Blueprint and them use in game?

Hi guys!!! Again…

As you can see in the images below, I created a construction script for the user to the editor, insert a static mesh.
So it is associated with static mesh the system to see how many elements there it.
Until then, fine.

The second part I created variables that the user can choose extra materials and would store it in the structure blueprint.
I can save these variables in the structure blueprint and then use them during the game?
