Unfortunately we don't have a workaround today, other than to use Excel 2011. What I can say is that our monthly updates allow us to ship new features to you as soon as they are ready
Just wanted to chime in and say that this feature is critical for us. We use it on almost every page we produce.
We have paid money for a subscription to your current product. Because this feature was missed (can't even imagine how that would be possible) we have had to move back to v.2011. We have been loyal to MS office on our Mac's since your first release...but
if we have to settle for a solution that does not completely fit our needs we may as well take another look at Apple Numbers! Please place a priority on this issue.
Please provide an ETA on when this feature might arrive so we can decide what our next step will be.
