Lunch and Break Scheduler

Good Morning all,

Thanks for checking my topic. I've searched the forums but have been unable to figure out any sort of solution...

I'm not exactly sure if something like this is possible, but I'm attempting to create a scheduling spreadsheet that automatically assigns breaks/schedules based off the following data.
I have 19 employees and am open from 9:00am-8:00pm. The start and end time of each employee doesn't matter, but each employee should work 8 hours M-F within the times we're open.
My employees get 2 15 minute breaks, then 1 30 minute lunch.
I cannot have more than 4 employees out at a time.

Would something like this be possible with Excel?

Thank you in advance!

The attached is not my creation. Can't recall where it came from. Note the many formulas that assign the breaks, etc.
