Is it possible to batch replace icons in multiple macros in KM 10?
If you copy ⌘C the icon from one Macro's icon Image Well, you can multiple select all the other Macros you want to have this icon (in the Macro Column) and press ⌘V to change them all in one step. I know this isn't a "batch" automated action but it still speeds up the process. I think this was introduced in KM10 or shortly before.
