Unsure how to add/update system wide speed dial codes

I am running FreePBX with the Mod - Speed Dial Functions

The previous person maintaining this Phone server was let go. I am trying to add a new speed dial extension to the moduel but I’m unsure how to do so. It looks like there may be a couple different ways to go about this so I wanted to ask if there was a standard way to add global speed dials. (Hopefully there is a config file I can manipulate). If that is not the case perhaps someone can tell me how else this might be done.

Thank you for your time.
