JP1 Remotes

I have an xsight remote. If I assign a macro to a softkey on the device, is there any way I can get a custom icon to show up? I know you can assign icons for specific functions of the remote, but what about macros?

I don't know of any way to assign an icon to a macro except for favorites. So a workaround would be to make a favorites device, then assign your macro step functions to digits 0-9, then make a favorite "channel" consisting of the desired digits.
