By adding a fixed value to the numbers, we get a number that has the zero in the right place. That is combined with the text “Image”. The column Combine was copied and converted to a text column, that can be fixed using Data > Find and Replace.
Here is what the Find and Replace interface looks like.
So if you did not have to do this too often this is not that many steps. If this is something you have to do all the time this might become tedious. Let us know how big of a need this is for you.
