In Calc, I have multiple groups of rows. I keep most of them hidden because it’s a large spreadsheet. However, when I want to expand a group, there is only one ‘+’ button, and clicking it will only expand the bottom-most group. I would like to reverse this, and have the ‘+’ button expand starting from the top-most row. Otherwise, is there an option to have a single ‘+’ button for each collapsed group, so I can choose which one to expand? It seems odd that I can collapse a specific group, but cannot choose which one to expand if I have multiple groups collapsed.
