Trying to update a date based on another date

[CYT_Sets]

Hello all,
I’m trying to automatically update a grid of available appointment times to reflect the current date with our appointment times, I can’t seem to figure this out on the formula side or the date list side of things. I tried to create a formula:

DATEADD({All Time Slots},1,‘days’)

And this keeps the same time slots as the previous day, but I can’t set an automation to use the formula field to update the ‘Time Slots’ field because it is a calculated value. How can I keep the appointment schedule grid updated with the current date and appointment times?
