They're called Pitchnames in S1. Click on the Pool tab on the right where you find your tabs for Instruments, Effects, etc. Log into the Exchange with your Presonus password. You'll find Pitchnames along with a ton of macros and other things that will make your life easier. Highlight the Pitchname you want. At the bottom, where you signed in, will be a description and an install button. This downloads it to the proper area. Then, just load the Pitchname in your MIDI editor. Once you do it, you'll see how simple it is. It's worth it to spend some time in the Pool and see what is on offer.
This shows how to load into the MIDI editor :
