Dropdown List To Define Name Of Cell Not Value?

I'm trying to create a drop down list that will define the name of the cell so I can reference it in formulas or codings to change the format of various cells defined by a specific name.

I'm not even sure if I can have multiple cells defined as the same name

I'll be inputting data into cells, and I want the color of the cell to change depending if the data is one of these criteria: 'In Service', 'In Transit', or 'Must Purchase'. I can't just make separate criteria columns to list all the data, because the data is already placed in a specific order. So I want whoever is viewing this to know which entry fits which criteria from the color of the cell.

The only thing I could think of is inputting the cell data value, and a drop down menu to define the cell name. I'll input a conditional formatting function to format based on the defined name criteria.
