Hi Gill,
Oh, I had assumed you were using a multiple, single value variable. You can cut and paste in that case. However, you screenshot looks to be complex variable and A-OLAP and A-Office don't allow you to paste in that case. Instead, you can add multiple values by pressing the "+" button and inserting a new value row.
I can see how that would be slower way of inputing your values. I'd suggest you enter an Idea Place suggestion for this http://goo.gl/bc0zib.
