Is there anyway to create a hover label that pulls its info from a separate worksheet?

For instance, i have a a workbook that has approximately 26 worksheets in it. 22 are essentially copies of each other (with separate purposes). I have 4 sets of columns on each and would like to be able to have it where when i hover over a cell, it references a cell on another sheet to pop up a description of what that cell is for. I know I could just add a column to each of the 4 sets to show the text, but that would take up too much space and make things too cluttered, and each sheet already takes up the full width of a legal size page in landscape with reduced margins.


Any ideas or suggestions?
