EasyGrepMode for current file only

I know that Vim has the ```:s``` to search and replace in the current file, and I use it a lot.
But it seems quite convenient to use easygrep interface also when I want to do the ```:Replace``` only in the current file.

Does it make sense to you?

To do it I guess that having a ```EasyGrepMode = 4``` for current-file-only should be the best way.

Thanks.
