Renumber sheets from selected

Add +1 to sheets from the selected, so you can add a new sheet inbetween.

Example

Your sheets numbered like this:

You want to add a new sheet numbered A02.

Run the script, select the current sheet A02, write "A" to the prefix box (without the quotation marks).

Your new sheet numbers will look like this: (Note the missing A02)

Now you can add sheet A02. It won't touch those sheets wich don't start with the aforementioned prefix.
