No Option to REMIND BEFORE Alarm Time

I love this alarm app, BUT I have set the alarm time before my actual meeting if I want to snooze a couple times before the meeting starts. Example: I have a meeting at 2:30, but i have to set the alarm for 2:15 to “remind” myself of the meeting. This creates confustion. The app should do this for me. To fix this, I’d like to be able to set my alarm for ACTUAL meeting time, then have a setting to REMIND me 15, 30, 45 minutes BEFORE, then allow me to “snooze”.
