formatting page numbers
 

I want to format a page number in a footer in Excel. In Word, there is a
function to format the page number, where a person can choose 1,2,3;
i,ii,iii, a,b,c; A,B,C; etc.

Does anyone know of a similar functionality in Excel? Specifically, I would
like to number the pages A, B, C, etc.

Thanks.
