insert a property line

Hi,

How can I insert another line in the custom properties tab. I need another line between Drawing No and Drawing Title. I know I could just add it at the end (line 10) but I want keep similar information together.

I thought it would work like Excel click a line and go insert to get a line above, but this doesn't seem to work

Thanks
