When I create a new Command Group, I can specify the Parameter Mappings for that Command (Type of Command Group: ExcuteAction).

However, I don’t see any option to change the Parameter Mappings of already created Command Group item. I’m in the Page Designer view of my Custom Page and all I need to do is I would like to amend some Mappings I entered when I initially create my Command Group.

Can you please advise how can I achieve this?
