prevent merged cells from splitting when printing
When you print a document in excel, have the option to prevent merged cells from splitting across pages (automatic feature, not by manually adjusting page breaks).
@Webber, I'd suggest maybe in Page Setup under 'Sheet' under print options. I think it makes sense to have this setting at a worksheet level, rather than for individual merged cells as that could get messy (and an administrative burden) if you have lots of merged ranges all over the sheet

Have a toggle on/off in the Merge Cell menu for this option, whether or not to allow merged cells to split at a page break.
