How do you add a Toolbox Fastener to the Smart Fastener feature library?

I have been looking for answer to this question everywhere and can't find an answer. I am not even sure if it is possible at this point, BUT if it were that would make my job a lot easier. I work for a smaller company and am the only drafter. Being able to make my own fasteners, or download them from McMaster and use them in the smart fastener feature would be a huge help.

So far I have only been able to add parts to the smart fastener library by copying some of the existing fastener files that come standard in the tool box, clearing out all the features and rebuilding the part file. 

Can someone please show/tell me an easier way to get part files that I add to the toolbox to populate the smart fastener library? Thank you!

Just for clarification, below are screenshots of toolbox standard parts  vs. parts that I copied from toolbox standard parts vs. parts that I made and imported into the design library. As you can see Heavy Hex Bolt lacks any indicator. Test_ai is a copied part that also lacks an indicator and has the same file format and configuration as a standard toolbox part. TEST 2023 and TEST 2024 are parts that I imported into the toolbox and are denoted with a little indicator. These parts do not have the configuration or format of the naitive toolbox fasteners.

 

 

These are screen shots of standard toolbox fastener configurations(A) vs parts that I make or download (B). I am trying to get my parts

To be formatted the same as the standard toolbox fasteners because those will populate the smart fastener library.
