Is there an macro feature to use SaveAs without opening the Save-Dialog?

I want to suggest:
document.SaveAs( [ strNEWName ] );

which saves the document with an new name "strNEWName"
as parameter and without asking for an new name via dialog.


Currently i do that by an macro in several steps:

strOrig = document.FullName;
document.Save(strNewName);
editor.OpenFile( strOrig );

.
