We've got ~60 employees and want to basically say, "Happy Birthday Steve" (or any other name) on the person's birthday so everyone knows. I was thinking of having a nice birthday themed background image and then overlaying the text and name linked to a csv/excel/google sheet document. The kicker is that I'd want that specific person's name only to appear on their birthday. I don't really have the time to compile 60 different slides all with different dates. Any help on this?
