Fastener Symbol for Toolbox Only?

I was really hoping that the toolbox would be a viable option for us, but after much research...it is EXTREMELY difficult to find anybody that has positive reviews about it at all!

So I am working on creating our own "toolbox" in the design library. I really like how the toolbox displays the bolt symbol in the model tree.

Is there any way to force it to display this or is it directly linked to the toolbox?
