Default Fade Settings

Hello All. I am using Premiere Elements 18 to make a video from my vacation pics. I added music to enhance the video, and I'd like to have the music fade in several places. I know how to get it to fade, but I'd like to change the default setting to make the fade longer. I've looked through the settings, but I can't figure out how to change the default. Does anyone have any suggestions? I know that I can manually change the timing of the fade, but I'd rather not do that.
