Let's say this upcoming thursday is wipe day (the 6th) and I want a different config for that one specific day. How about a data folder with folders numbered 1-31 and each one of those folders have their own timedexecute json? If most days are the same, just copy and paste the same config to all the folders and edit the one you want that's different (for wipe day)? You can have an option in the main config "use month days config: true/false"

This would be great!

sounds great.  or the same like TruePVE
where the number in front of the time represent the day
0.16:00 = Sunday 16 O clock
1.22:00 = Monday 22 O clock
and so on.. so we can use the all days in a week anothers timers
