Displaying custom dynamic data on a second time header (Scheduler)

I can currently only pass constants to display on this extra row, but I have precalculated array for every date in the month, and would like to iterate through the data displaying each on its appropriate date.

As seen on this picture, am able to display B for Bullseye through this snippet here.

I figure I can display data like count in table data array here? or can i add a custom header thats not necessary a time one?
