MMM-GoogleTasks - show Completed until next day starts

[Hooch_]

I assume this is possible but I can’t figure out the coding - very new to MM and JS. Any help will be appreciated.

I have a task list with mostly recurring tasks but each day 1-3 non-recurring tasks get added to the list. With

showCompleted: true,

all tasks show throughout the day, then at some point overnight the Completed recurring tasks drop and get replaced by the Incomplete task for the new day. However, all the non-recurring tasks stay so that after a few days there’s along list of Completed tasks. How do I have all Completed show until the end of the day, midnight, whatever, then have the non-recurring drop along with the recurring?
