You can also duplicate the macro, deselect all options up to the point of insertion, save the macro, edit the duplicate deselecting all the actions from insertion to end, save macro and then run macro 1, add necessary actions, run macro 2 and save.
Thatll minimize duplicate entries.
That said, I’ve found that macros should really be minimized to between 5-10 actions max and then several bundled in a folder as a workflow. It makes the editing process a lot easier and gives more flexibility during an edit.
Having more than 10 actions begins to become a “one click” edit approach
