I have a worksheet set with = reference to a cell in another worksheet.
Conditional formatting is set to color the cell if the value is greater than
0.
Is there a way to add to the conditional formating to the same cell that
will color the cell a different color if the value is input and not from the
formula?

My goal is to identify cells that have had their formula overwritten with
manual input. There are times a manual input needs to be entered and I need
to visually see which cells are not based on a formula. I don't want to set
protection on.
