Exporting and Importing Percussion Kits

Hi there, I found a great resource of MIDI projects that I want to use for this arrangement I am doing. I was able to export the percussion kit as it is significantly different from the default drum kit. I am wondering if there is a way to (a) import the kit and (b) change my current drum kit to said imported kit. I’m staring at the dialog box but do not see an option to change to any preset kits, etc. Any help is greatly appreciated. Thank you in advance!

Nevermind! I figured it out!
