   > The idea would be to allow a list of cron expressions as a `schedule_interval`. For example, the scheduling in the description would be defined as `schedule_interval = ['30/10 16 * * *', '*/10 17 * * *', '0,10 18 * * *']`. Do you think this is the way to go?
   
   This will be of great help. Instead of creating separate DAGs for the same job (like what currently I am doing), this would reduce to just 1 DAG taking care of multiple schedules. One workaround right now is if the crons are not strict, one can tweak multiple crons to have the minutes dimension same for all, for ex : "45 0,8,13 * * *", this will run for 0045, 0845 and 1345 Hrs respectively.
   Unfortunately, the crons in my case are strict (0100, 0815 and 1330 Hrs), hence have to create 3 separate DAGs. 
   Enabling schedule interval to accept list of crons would be very helpful :) 👍
