In EXCEL, how to use INSERT/NAME subcommand CREATE?
 

I need to define a set of Named cell ranges referring to the same area in a
set of worksheets. I can do this, but only laboriously, using
Insert/Name/Define.

But there is another subcommand Insert/Name/CREATE which looks as if it
might make the task easier and so more foolproof. But I cannot find any
documentation on this command. When I try it out, it either returns a
meaningless error message, or does nothing. And there is nothing in HELP to
help.

Can anyone tell me where I can find the documentation for this subcommand?
