Can I paste info into comments box on Excel
 

I have around 70 cells that I want to either have a clickable link to other
info elsewhere in a workbook or alternatively to show that info in a comment
box. But I can't find a way to do the 1st and the 2nd seems to involve a lot
of typing as I can't paste into the comments boxes. Any Ideas please, or
will it look too messy anyway with all those comments boxes?
