Hello @Tom_Mohr!
This is actually possible today if you first make a button, then use the Button() formula in your table to reference it. Please note this functionality is still being tested and changed, so could break your doc (more on that here).
Another option is to simply use conditional formatting to just make changes to the cell behind the button, thanks! Also, please note, in my example I used “controlToday” instead of Today() in my formulas so it will still be a good reference example once all the tasks have become overdue. You can change the date at the top of the document to see how different days would be interpreted as time would pass.
