May I suggest a setting (IFORGOT) for a timer to make phone automatically go from silence to sound ?o

I am a college student and I put my phone silence for classes from morning to mid afternoon. However I forget to take my phone off silence and turn it to sound and so this is an inconvenience to my alerts in calendar events which I assign specific sounds for. I was wondering if there is by any chance that you could take the time to upgrade this setting into calendar or under a new settings section called (I suggest ) : IFORGOT

PLEASE !!!

THIS WOULD BE AMAZING FOR FELLOW STUDENTS IN EDUCATION, TEACHERS FOR LUNCH TIME . BUSINESS PERSONELLE FOR LUNCH AFTER MEETINGS !!!!

I Would love you guys more
