Evil, emulate Vim gdefault option

Hello,  Vim has an option       set  gdefault to include the g option as default in the substitute :s command, i.e.  to write:    1)   :%s/pattern/replace but meaning instead    2)   :%s/pattern/replace/g Also IIRC  gdefault reverses the effect of g, ie. adding it results in command 1). Is there a way to set the same option in Evil? Thank you and great work with Evil, Giovanni Maggiorani
