(English is not my native language so the question below maybe very confusing... please tell me so I can ask it in a "better way" )

I want to add a bolt into my assemble, but sometimes the smart fastener just get stupid (i.e. holes used by the smart fastener is out of alignment)

So I wonder is there any way to add a system fastener without smart fastener.

In a sample assemble I find a different way to add fastener:

It shows like a bolt + a little feather.

What does both mean?

(I have saw the bolt symbol before, but I have never seen the blue feather symbol.)

If I download a screw from the internet and add it manually, it shows like a normal part.

Can any 1 tell me how can I do it?
