very often you want to closely replicate another Axis object in a graphical table and make slight adjustments. At the moment this is difficult because there is no duplicate option. You have to copy and paste the expression from one Axis object to another.
In one of my dashboards, I have a graphical table with 49 axis objects that are slight variants of 8 items. The table is very time consuming to create and update, somewhere upwards of 3 hours. This would be a big time saver for me.
