I have cells (9x9 rows/cols), and I'm trying to create one cell out of the 49 cells to be unique, as you can see when you run the snippet, the cells have random numbers between 20 to 200, and one of these cells have Red color.
The problem I'm struggling with, I want that one cell to have Symbol (marking plate) like S or D for example instead of number, How i can achieve that?
