Validation List Question

[KuraiChikara]

I was wondering,
Is it possible within a Data Validation List, if you select an option in the top cell, for it to change the entire column to that option?

Example:
Say you have fruits in the list in column A:
Apples
Kiwis
Watermelon

But it goes down 100 Rows.

Is it possible to Change Apples to Kiwis in Column A2 and have it change ALL apples to kiwis going down (A3-A100)?

I'm sorry, I figured out my issue. I'm over complicating things. What I can do is change the top item and if it needs to be duplicated just double click the bottom corner of the cell to copy the data down.
