I love the ability to add several children at once but I would like to be able to copy repeating data such as Town/City or County/State which is often the same. This is a spreadsheet type entry and should be easy enough to drag and copy data as you would in Excel.
OK, I know you're going to say 'copy 'n' paste' but this is still a laborious way to do it when you often have several columns of data to add
