965 notifications and spotify

Hello.  I have a few questions.  While running, notifications (text messages & email) will pop up and block the top part of the watch screen.  I like seeing the notifications.  I don't like seeing them for 30 seconds.  Q1: Is there a way to decrease the display time to 5 to 10 seconds?  I recently ran a race.  I manually turned off all notifications.  While running, spotify came to the end of one podcast and should have started the next podcast on the playlist, but instead went silent (nothing played).  Q2:  Is this normal behavior or can this be fixed?  Q3: If we can turn off notifications, and if we can keep spotify functioning properly, can we set up a "activity" called "race" where notifications are off?  (There would be a separate activity "run" where notifications are on)
