Disable drag & drop warning: "There's already data here. Do you want to replace it?"

All,

I have a worksheet with no macros or VBA.

I want to allow users to drag any cell with data and drop it on any other cell with data, and not get the warning, "There's already data here."

I know there are a million ways to get data from one cell to another without using drag & drop, but the people who will be using this worksheet use drag & drop and prefer it.

Thanks!!

Jay
